Bug 279700

Application: krita (2.3.3)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic-pae i686
Distribution: Ubuntu 11.04

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

Via 'Comic Template' select 'Manga Template'. In Canvas, select the second tool from the toolbox and draw a line. Now, using the cursor try dragging the line from between, either normally or by pressing Ctrl+Click and dragging. Program crashes.

The crash can be reproduced every time.

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