Bug 318541

Application: krita (2.6.1)
KDE Platform Version: 4.10.2
Qt Version: 4.8.3
Operating System: Linux 3.5.0-27-generic x86_64
Distribution: Ubuntu 12.10

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

I had an image open, and I right-clicked a few times - The color-picker popped up.
I double-clicked after that, and Krita crashed.

I've tried to redo the same set of actions to reproduce the issue, but Krita hasn't crashed since then.

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