Bug 478810

Application: kate (23.08.1)

Qt Version: 5.15.10
Frameworks Version: 5.110.0
Operating System: Linux 6.5.0-14-generic x86_64
Windowing System: X11
Distribution: Ubuntu 23.10
DrKonqi: 5.27.8 [KCrashBackend]

-- Information about the crash:
Sometimes I'm just saving a trivial bash script or text file. I've never seen kate die for such apparently flimsy reasons as it has been in the last few weeks; probably coincides with kernel linux-image-6.5.0-14-generic

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
