Application that crashed: kdevelop
Version of the application: 3.9.94 (using KDevPlatform 0.9.94)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.2-desktop-0.rc1.1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
Attempted to open a file, a warning dialog appears explaining that it is marked as UTF8 but contains invalid characters, corruption may occur etc. Choosing to proceed results in a segfault. This is 100% reproducible.

 -- Backtrace:
