KDE Platform Version: 4.8.4 (4.8.4)

-- Information about the crash:
- What I was doing when the application crashed:
I had 3 small projects opened, nothing fancy. It already happened a few times in the last few months however I didn't have debug symbols installed yet. Sorry if it's duplicate but I don't understand anything from backtraces:)

The crash can be reproduced some of the time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Aborted
