Bug 451051

Application: konversation (1.8.21081)

Qt Version: 5.15.2
Frameworks Version: 5.86.0
Operating System: Linux 5.13.0-32-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 moving a PM conversation in the list up, using ALT-SHIFT, and after doing this for a couple of seconds, Konversation crashed.

This has happened to me before.

The reporter is unsure if this crash is reproducible.

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