Application: krita (2.9 Pre-Alpha (git 276a95e))
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-19-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
I had a default template open, and then attempted to use close so I could open a different file in the instance. It resulted into a crash for at the least 2 times.

The crash can be reproduced every time.

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