Bug 449416

Application: konversation (1.8.21081)

Qt Version: 5.15.2
Frameworks Version: 5.86.0
Operating System: Linux 5.13.0-28-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.5
Distribution: Ubuntu 21.10

-- Information about the crash:
- What I was doing when the application crashed:
I was using Konversation, and it had been open for a while, which it normally is. I tried to move the Window, and it crashed pretty much immediately.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Konversation (konversation), signal: Segmentation fault
