-- Information about the crash:
- What I was doing when the application crashed:
Probably it is katepart problem, but I haven't tried.
I edited python code, paste a class method and change it a little,
next collapsed it and I saw that one empty line between this and next method is
collapsed too.
SO I want to editor refresh view so I tried to reopen file, then editor
crashed.
The crash does not seem to be reproducible.
