Bug#1107868: mumble: segfault on first start
severity 1107868 important forwarded 1107868 https://github.com/mumble-voip/mumble/pull/6852#issuecomment-3070250752 thanks I'm lowering the severity of this bug from "serious" to "important". The justification is that this bug causes a Segfault in specific cases where PipeWire libraries are installed without configuration installed, rather than making package unusable to everyone. https://www.debian.org/Bugs/Developer#severities Upstream is working on the bug but the specific problem is not clear, and I don't think this bug is worth removal of the package for everyone in Debian on July 26. We're close to the next release and I would rather not risk Mumble not shipping at all over this. Mumble can be updated in a Point Release for this issue. -- Chris Chris Knadle [email protected] On 7/14/25 12:54, Chris Knadle wrote: I've forwarded the additional bug information upstream to see if additional fixes can be done for this bug.

Greetings. Upstream found the bug in the variable name based on Philipp Kern's backtrace from Debian Bug #1091358 https://github.com/mumble-voip/mumble/pull/6852/commits/cd4acaaec3b1b1b7ec7b8819a6f7ac2d81ea14f1 I'm working on an upload. -- Chris Chris Knadle [email protected] On 6/28/25 20:50, Thorsten Glaser wrote: On Sat, 21 Jun 2025, Chris Knadle wrote: The ALSA backend is supported, and depends on it, and loads other audio libraries if they are found (PipeWire, PulseAudio, JACK) -- but if PipeWire is found it prioritizes that over ALSA.

Bug#1107868: mumble: segfault on first start
tags 1107868 + moreinfo thanks Hello Thorsten. Upstream responded with information about this bug. The ALSA backend is supported, and depends on it, and loads other audio libraries if they are found (PipeWire, PulseAudio, JACK) -- but if PipeWire is found it prioritizes that over ALSA. So in this case it looks like libpipewire-0.3.so.0 and libpulse.so.0 are found, so Mumble tries to connect to pipewire, but then the PipeWire configuration pw.conf isn't found, leading to a Segfault. Upsgream would like to fix the bug and they are requesting a coredump and/or a backtrace, if that can be provided. I believe a coredump can be created by executing 'ulimit -c ' in a terminal and then executing mumble afterwards in the same terminal session (assuming the shell used includes ulimit, such as bash). Apparently 'ulimit -c unlimited' can be used to allow any size coredump.

Bug#1107868: mumble: segfault on first start
Hello Thorsten. This error log shows that there's a failure to load pw.conf for PipeWire. Philip Kern ran into the same problem in #1091358, so this is a duplicate report. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1091358 In that bug we found that piprewire-pulse does not have a dependency on pipewire-bin, but pipewire has a dependency on pipewire-bin. I think this bug needs to be redirected to piopewire-pulse. I'll also try touching base with Mumble upstream about it. -- Chris Chris Knadle [email protected] On 6/16/25 06:06, Thorsten Glaser wrote: Package: mumble Version: 1.5.735-4 Severity: important X-Debbugs-Cc: [email protected] Freshly installed: $ mumble Dir didn't exist: /home/tg/.local/share/data/Mumble Successfully migrated data directory 2025-06-16 12:04:45.005 JACK 1.9.22 from libjack.so.0 2025-06-16 12:04:45.022 PipeWire 1.4.2 from libpipewire-0.3.so.0 2025-06-16 12:04:45.048 PulseAudio 17.0.0 from libpulse.so.0 2025-06-16 12:04:45.049 PulseAudio: Connection failure: Connection refused 2025-06-16 12:04:45.062 Theme: "Mumble" 2025-06-16 12:04:45.062 Style: "Lite" 2025-06-16 12:04:45.062 --> qss: ":themes/Default/Lite.qss" 2025-06-16 12:04:45.070 Locale is "C" (System: "C") 2025-06-16 12:04:45.070 Unable to find bundled translations for locale "C" 2025-06-16 12:04:49.173 Database SQLite: "3.46.1" 2025-06-16 12:04:49.353 Updating application palette 2025-06-16 12:04:49.510 GlobalShortcutX: Using XI2 2.4 2025-06-16 12:04:49.685 QMetaObject::connectSlotsByName: No matching signal for on_qtvUsers_customContextMenuRequested(QPoint,bool) 2025-06-16 12:04:49.686 QMetaObject::connectSlotsByName: No matching signal for on_muteCuePopup_triggered() 2025-06-16 12:04:49.928 AudioInput: Opus encoder set for high quality speech 2025-06-16 12:04:49.928 AudioInput: 4 bits/s, 48000 hz, 480 sample [W][12:04:49.936583] pw.conf | [ conf.c: 1182 try_load_conf()] can't load config client.conf: No such file or directory [E][12:04:49.936617] pw.conf | [ conf.c: 1215 pw_conf_load_conf_for_context()] can't load config client.conf: No such file or directory [W][12:04:49.937180] pw.conf | [ conf.c: 1182 try_load_conf()] can't load config client.conf: No such file or directory [E][12:04:49.937436] pw.conf | [ conf.c: 1215 pw_conf_load_conf_for_context()] can't load config client.conf: No such file or directory Segmentation fault (core dumped) -- System Information: Debian Release: 13.0 APT prefers testing-security APT policy: (500, 'testing-security'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 6.12.30-amd64 (SMP w/2 CPU threads; PREEMPT) Kernel taint flags: TAINT_WARN Locale: LANG=C.UTF-8, LC_CTYPE=C.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: sysvinit (via /sbin/init) Versions of packages mumble depends on: ii libasound2t64 1.2.14-1 ii libavahi-compat-libdnssd1 0.8-16 ii libc6 2.41-8 ii libgcc-s1 14.2.0-19 ii libopus0 1.5.2-2 ii libpocofoundation100 1.13.0-6+b2 ii libpocoxml100 1.13.0-6+b2 ii libpocozip100 1.13.0-6+b2 ii libprotobuf32t64 3.21.12-11 ii libqt5core5t64 5.15.15+dfsg-5 ii libqt5dbus5t64 5.15.15+dfsg-5 ii libqt5gui5t64 5.15.15+dfsg-5 ii libqt5network5t64 5.15.15+dfsg-5 ii libqt5sql5-sqlite 5.15.15+dfsg-5 ii libqt5sql5t64 5.15.15+dfsg-5 ii libqt5svg5 5.15.15-2 ii libqt5widgets5t64 5.15.15+dfsg-5 ii libqt5xml5t64 5.15.15+dfsg-5 ii libsndfile11.2.2-2+b1 ii libspeechd20.12.0-4 ii libspeexdsp1 1.2.1-3 ii libssl3t64 3.5.0-2 ii libstdc++6 14.2.0-19 ii libx11-6 2:1.8.12-1 ii libxi6 2:1.8.2-1 ii lsb-release12.1-1 mumble recommends no packages.

And, of course, the next start just crashes as well.
