-- 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
