Bug 467722

Application: neochat (23.01)

Qt Version: 5.15.8
Frameworks Version: 5.104.0
Operating System: Linux 6.2.7-200.fc37.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.27.3 [KCrashBackend]

-- Information about the crash:
Whenever I try and leave a room that is from my Slack bridge, the application crashes shortly afterwards. I am not sure if this happens when I leave a room from other bridges (irc, gchat) or matrix itself as I haven't tried yet.

The crash can be reproduced every time.

-- Backtrace:
Application: NeoChat (neochat), signal: Segmentation fault
