Bug 310120

Application: krita (2.3.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-26-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I used the eraser of my tablet pen and then clicked the brush selection drop down menu and then Krita crashed.

- Custom settings of the application:
I had just finished changing the pressure settings of my Wacom tablet prior to using Krita for the first time.

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