Application that crashed: kdevelop

Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64

What I was doing when the application crashed:
Opening kdevelop goes right but when i want to open any source file it crashes. I'va deleted .kdevchain, and config files from /home/.kde but nothing helps.
