-- Information about the crash:
- What I was doing when the application crashed:
I was editing normal text file (with unicode box drawing characters). I copy-pasted the file contents into my browser, came a back little later and used F4 to close kate, choose "Do not save" when asked what to do with unsaved changes.

-- Backtrace:
