Hello Michael! Thanks for your prompt reply :) Okay that makes sense. How do I install debuginfo for webkit though? Looking into apt, all I can find is this: apt-cache search debuginfo debugedit - tools for handling build-ids and paths rewriting in DWARF data libdebuginfod-common - configuration to enable the Debian debug info server libdebuginfod-dev - libdebuginfod development libraries and header files libdebuginfod1 - library to interact with debuginfod (development files) debuginfod - debuginfo-related http file-server daemon And webkit: apt-cache search debug | grep -i webkit python3-pyqt5.qtwebkit-dbg - Python 3 bindings for Qt5's WebKit module (debug extensions) Looking around in google sends me a lot of python/QT-related links to some (old?) packages that I don't think are related: https://www.google.com/search?q=webkit+debuginfo Maybe I should install libdebuginfod1, libdebuginfod1-dev and debuginfod, then try again? Thanks again! -Alemar El vie, 20 ago 2021 a las 18:24, Michael Catanzaro () escribió: > > On Fri, Aug 20 2021 at 11:27:17 AM -0600, Alemar > wrote: > > #2 0x7fcfd172ff2b in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #3 0x7fcfd37e0622 in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #4 0x7fcfd37efef6 in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #5 0x7fcfd31529a6 in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #6 0x7fcfd315321a in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #7 0x7fcfd2c5b9fd in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #8 0x7fcfd2c5cf0f in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #9 0x7fcfd3095412 in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #10 0x7fcfd30954e6 in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #11 0x7fcfd30c00b4 in () at > > /lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37 > > #12 0x7fcfd073d025 in () at > > /lib/x86_64-linux-gnu/libjavascriptcoregtk-4.0.so.18 > > #13 0x7fcfd073d2a3 in () at > > /lib/x86_64-linux-gnu/libjavascriptcoregtk-4.0.so.18 > > Hi, it looks like you're missing debuginfo for WebKit.

Re: [webkit-dev] [Help] WebProcess CRASHED
Hello Michael, Sorry for the late reply, now is when I had time to run the debugging instructions. Here's the full stack trace, I don't see any "???" frames so I think it's all good. Also, sorry for my lack of mailing-list-netiquette, I don't know if I should attach a file or send it all as text instead. Since it's not too large, I'm sending it here as text.

Hi, you need to get a backtrace with gdb. There are some instructions here: https://wiki.gnome.org/GettingInTouch/Bugzilla/GettingTraces Michael ___ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
[webkit-dev] [Help] WebProcess CRASHED
Hello list! Currently I'm having a problem with the library when going to www.bing.com (it seems to happen only on that site though), where the browser process crashes. I thought it was my app, but when running it against the MiniBrowser, it also crashes! >From the developer tools, I'm suspecting it could be related to trying to load (and play?) an mp3 file (start.mp3). The current PC it's running on is a brand-new installed Ubuntu 21.04 up-to-date which seems to use the libwebkit2gtk-4.0-37 library. Such a PC does not have any audio drivers installed, I'm basically running off Ubuntu Server with X11, Openbox and NVIDIA drivers, nothing more, nothing less. I suspect it could be because it's trying to play the audio file but it can't. However, the log does not show much: (MiniBrowser:72279): dbind-WARNING **: 18:07:43.671: AT-SPI: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files (WebKitWebProcess:72294): dbind-WARNING **: 18:07:43.752: AT-SPI: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files (WebKitWebProcess:72393): dbind-WARNING **: 18:08:25.851: AT-SPI: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files (WebKitWebProcess:72420): dbind-WARNING **: 18:08:27.415: AT-SPI: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files ** (MiniBrowser:72279): WARNING **: 18:08:27.499: WebProcess CRASHED Is there any way I can try to get more debugging info for you guys to see if I can fix the problem on my own, but also without building the full webkit library as it's really heavy and time-consuming?
