Bug 334497

Application: krita (2.9 Pre-Alpha (git 043fcc2))
KDE Platform Version: 4.11.4 (Compiled from sources)
Qt Version: 4.8.5
Operating System: Linux 3.12.13-desktop-2.mga4 x86_64
Distribution: "Mageia 4"

-- Information about the crash:
- What I was doing when the application crashed:
I started Krita and created a new file. Crash was immediate. I reproduced this behaviour and noticed that it also happened when opening a file.

The crash can be reproduced every time.

-- Backtrace:
Application: Krita (krita), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
gobject.pyc: gdb was not built with custom backtrace support, disabling.
