Description William 2019-12-01 19:45:11 UTC

SUMMARY
I started Konversation, connected to a server, joined a couple of channels and minimized the window. While I was using another app (firefox, the last time), Konversation crashed.
This has happened both on Windows 10 (1909) and openSUSE Leap 15.1, both times running the 1.7.5 version. The Windows version was downloaded from https://binary-factory.kde.org/.

STEPS TO REPRODUCE
1. Open Konversation;
2. Connect to a server and join a channel;
3. Minimize Konversation;
4. Wait a few minutes (about 20 to 40 minutes(?) - it's not constant) until it crashes.

OBSERVED RESULT
Konversation crashes silently. The last time (in openSUSE), I ran it from the console to check if I got an error to display there, and it actually brought up the KDE crash reporter; The generated report is pasted under "Additional Information".

EXPECTED RESULT
Keep Konversation running.

Comment 1 Sam Wilson 2021-06-12 08:30:38 UTC

I've noticed this happening usually a few minutes (or less) after waking the system from sleep. Konversation looks fine, but as soon as I interact with it it crashes with:

Connection broken with state 5 and error: "The remote host closed the connection"
KCrash: crashing... crashRecursionCounter = 2

Comment 2 Friedrich W. H. Kossebau 2021-12-19 15:24:07 UTC

Thanks for the report. While the backtrace sadly lacks the needed info for the chain of calls ending up in the crashing operator== call, the present calls and the crash description hint this is the same cause as for the fixed bug 437595, so closing as duplicate.

Please reopen if still seeing with versions >= 1.8.21080.
