Description Szőts Ákos 2020-01-09 20:02:05 UTC
Application: plasmashell (5.17.4)

Qt Version: 5.13.1
Frameworks Version: 5.65.0
Operating System: Linux 5.3.12-2-default x86_64
Distribution: openSUSE Tumbleweed

-- Information about the crash:
- What I was doing when the application crashed:

I tried to log out of KDE via the Start menu but it just made the KWin decoration disappear, the desktop itself remained there.

Therefore, I Ctrl+Alt+Backspace'd and restarted X server. After logging in again from the login manager DrKonqi waited me with its icon that Plasma crashed.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
