Application: krita (2.8 Pre-Alpha)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-30-generic x86_64
Distribution: Ubuntu 13.04

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

Open the Brush Creator directly after launching Krita, no preset chosen. Directly choose the Textbrush Tab. Deleted half of the default Text with default Font (Ubuntu, 9) -> Crash

3 Crashes so far after different amount of time playing with the Textbrush, without any idea what could trigger it.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Krita (kdeinit4), signal: Aborted
