Application: kdevelop (4.1.0)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-23-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I started KDevelop from the K menu, with an existing session which had been open when I closed KDevelop last time. KDevelop showed the splash screen, showed the dialog for an unknown file type (.pro) asking if to load it as text, and then crashed, before I did any input.

Sorry, no time to debug this myself atm :(

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
