Application that crashed: kdevelop.bin
Version of the application: 3.9.98 (using KDevPlatform 0.9.98)
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I've closed the program using cross on the window frame and crash occured. After updating and recompiling, and running ..sycoca another time I wanted to ensure in proper highlighting inside the editor. Highlighting and navigation worked properly, so I just closed. The project I used consists of several files, nothing enormous.
