Application that crashed: kdevelop
Version of the application: 3.9.94 (using KDevPlatform 0.9.94)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-ARCH i686

What I was doing when the application crashed:
Kdevelop4 (trunk) crashed after I opened a file with broken UTF-8 encoding. The message box with the information popped up, and the crash happened when I pressed OK.

Steps to reproduce:
1) Create a file with broken UTF-8 encoding in some application
2) Open it in KDevelop
