Bug 274907

Application: krita (2.4 Alpha 1)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

Testing krita-ui_improvements-silvioheinrich

Open Krita, create new document, select sketch brush , try to draw : crash
(only if I do select other things before, like change blending mode, presets, other brush engines, then select sketch brush it doesn't crash.. only if I select it at first)

The crash can be reproduced every time.

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