Application: krita (2.7 Pre-Alpha)
KDE Platform Version: 4.9.4 (Compiled from sources)
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic x86_64
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- What I was doing when the application crashed:
While using the textline edit tool for editing text, using Ctrl+Z multiple times(or the same number of times as the length of the text you entered), Krita crashes

The crash can be reproduced every time.

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