Application that crashed: krita
Version of the application: 2.1.0
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I've modified a PNG- picture, that was approximatly 15KB large. When I closed Krita without saving my changes, it crashed. If I remember right, it wasn't even asking me if the changes should be saved.

 -- Backtrace:
Application: Krita (kdeinit4), signal: Segmentation fault
