Discord and several other applications using libappindicator are widely reported to have been crashing for several years. See: https://github.com/flathub/com.discordapp.Discord/issues/30 (and others) [ Test case ] - Run discord application - It must not crash in ubuntu (or when indicators are enabled) [ Regression potential ] Very low, icons might not appear in some cases, if any. ----- This is the backtrace: (gdb) bt full #0 0x00007fe1d5d2e00e in () at /app/lib/libappindicator.so #1 0x00007fe1f5a6f3c5 in g_closure_invoke () at /lib/libgobject-2.0.so.0 #2 0x00007fe1f5a813d2 in () at /lib/libgobject-2.0.so.0 #3 0x00007fe1f5a8a02c in g_signal_emit_valist () at /lib/libgobject-2.0.so.0 #4 0x00007fe1f5a8a40f in g_signal_emit () at /lib/libgobject-2.0.so.0 #5 0x00007fe1d5d2ed4f in app_indicator_set_icon_full () at /app/lib/libappindicator.so #6 0x000000000077851a in () #7 0x0000000001de7123 in () #8 0x0000000001e4bd4e in () #9 0x0000000001e6e34c in () #10 0x0000000001e6e668 in () #11 0x0000000001e6e9cb in () #12 0x0000000001df971a in () #13 0x00007fe1f354b1c7 in g_main_context_dispatch () at /lib/libglib-2.0.so.0 #14 0x00007fe1f354b430 in () at /lib/libglib-2.0.so.0 #15 0x00007fe1f354b4dc in g_main_context_iteration () at /lib/libglib-2.0.so.0 #16 0x0000000001df9606 in () #17 0x0000000001e6e0e7 in () #18 0x0000000001e29570 in () #19 0x0000000000c37ec8 in () #20 0x0000000000c37d15 in () #21 0x0000000000c1da7d in () #22 0x0000000000a9282e in () #23 0x00000000007892d4 in () #24 0x00000000007896e0 in () #25 0x0000000003b830a3 in main () Happens in all versions of libappindicator built from latest sources available on launchpad. I ran into the issue yesterday when installing Discord for the first time. I have tracked the problem down to libappindicator passing in an extra vararg item to g_signal_emit that the signal's definition in libappindicator was not declaring, causing the crash you see above in gobject's g_signal dispatch machinery. Patch is attached. I am presuming this is 'upstream' for libappindicator, whatever that may mean for what appears to be an unmaintained project. If it is not, and since it is an Ubuntu/Canonical-sourced project originally, I respectfully request that you assist in upstreaming it since this bug is causing severe breakage for users across all distros. ** Affects: libappindicator (Ubuntu) Importance: Undecided Assignee: Marco Trevisan (Treviño) (3v1n0) Status: Fix Released ** Affects: libappindicator (Ubuntu Bionic) Importance: Undecided Assignee: Marco Trevisan (Treviño) (3v1n0) Status: Fix Committed ** Affects: ubuntu-translations Importance: Undecided Status: New ** Tags: patch verification-done-bionic -- Segfault in app_indicator_set_icon_full [patch attached] https://bugs.launchpad.net/bugs/1867996 You received this bug notification because you are a member of Ubuntu Translations Coordinators, which is subscribed to Ubuntu Translations. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-translations-coordinators Post to : ubuntu-translations-coordinators@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-translations-coordinators More help : https://help.launchpad.net/ListHelp
