Application: palapeli (1.2)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-25-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to create a puzzle and every time I used a specific black and white image, Palapeli crashed, but I was able to create a different puzzle with the same parameters using a coloured image.

The crash can be reproduced every time.

-- Backtrace:
Application: Palapeli (palapeli), signal: Segmentation fault
