Bug 447748

Application: konversation (1.8.21081)

Qt Version: 5.15.2
Frameworks Version: 5.86.0
Operating System: Linux 5.13.0-23-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 had just replied to a PM in Konversation, normally Konversation runs fine, and this instance had been running for at least a day. I keep it running sometimes for weeks at a time. But for some reason, this time it crashed after sending the message. The window just disappeared, and then the KDE crash report assistant appeared in my system tray.

There is a good quality stack trace attached, and I'm available via email should further details be requested.

The reporter is unsure if this crash is reproducible.

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