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 [KCrash Handler] #4 ViewContainer::rowCount
