Qt Version: 4.6.2
Operating System: Linux 2.6.32-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
While opening (or more likely navigating to open) a document, kate crashes. This happens frequently but not systematically.

 -- Backtrace:
Application: Kate (kdeinit4), signal: Segmentation fault
