Application that crashed: kdevelop.bin
Version of the application: 3.9.99 (using KDevPlatform 0.9.99)
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
KDevelop (3.9.99 from svn) crashes when I try to open any file (.cpp and .h files for what it is worth) either via the file->open dialog or directly by double-clicking in the project overview. This bug is reproducable.

Cheers,
Oliver
