Bug 475630

Application: kate (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.5.0-2-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
if I accidentally hit the compose key and then undo, I find that my undo history becomes corrupted. This particular time, it actually crashed after accidentally hitting it.· I'm on bookworm, so this is the most recent stable Debian. I have not noticed this flaw in "Bullseye"

The reporter is unsure if this crash is reproducible.

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