Bug 460830

Application: neochat (22.09)

Qt Version: 5.15.6
Frameworks Version: 5.99.0
Operating System: Linux 5.14.21-150400.24.21-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.4"
DrKonqi: 5.26.1 [KCrashBackend]

-- Information about the crash:
Neochat would crash immediately after the user enters the password to their Matrix account, within the 'Login' setup page. It is reproducable on every run. There are no issues in my Matrix account, as I can login with the Element online client just fine. According to Element's 'Security and Privacy' settings category, Neochat DOES indeed show-up as a logged-in device. However, as mentioned before, it always crashes before it can show anything.

The crash can be reproduced every time.

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