-- Information about the crash:
KDE Konsole crashes ocassionally. I have observed also tabs in chromium browsers crashing, that issue is currently unresolved as I do not have the debug symbols for it and the error is non specific (SIGINT and SIGSEG) in optimized code. I currently suspect it may be related to intel or nvidia specific instructions being tried to be called on my amd system (AMD CPU without iGPU and AMD GPU), as thouse errors mostly occure for video streaming or when pages load/refresh. Also I could observe some glitches in page rendering which would also fit. However thouse creashes were lessoned when in debug mode which could also point to something more neverious like a compiler/linker optimization issue, however that's currently just speculation.

For this crash however if it is not related to rendering it is almost certainly unrelated to the above issue. Because of the above issue however I can also rule out many/most hardware defects. Like memory tests were ok, cpu stresstests were ok, storage was reduced and now only has a single NVME (which also was ok when last tested).

The last thing I did within Konsole before it crashed was having an interactive pwsh started and reading some of its Get-Help entries. But even if pwsh would have crashed, it wouldn't have crashed Konsole, so that's probably unrelated to this issue.

I also should note that I've seen console crash occassionally in the past few weeks too, I couldn't pinpoint anything specific though. But it only happened once or twice, so I ignored it for the most part. However now that it crashed again I wanted to take the time to create a bugtracker account and submit the details about the crash as it probably is not just a one off fluke.

The crash can be reproduced sometimes.
