-- Information about the crash:
- What I was doing when the application crashed:
I had two projects open when I closed kdevelop. I did a restart of my computer and then In tried to start kdevelop. It crashed twice in a row while during application startup. The third time it worked again.

The crash can be reproduced some of the time.
