Application: krita (2.4.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic i686
Distribution: Linux Mint 12 Lisa

-- Information about the crash:
- What I was doing when the application crashed:
Editing an image.

- Unusual behavior I noticed:
Perhaps the problem would be when importing image files (mostly svg and sometimes png) and dragging the layer (from the layers widget) from a window to another.

The crash can be reproduced some of the time.

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