Application: krita (2.6.4)
KDE Platform Version: 4.10.5
Qt Version: 4.8.5
Operating System: Linux 3.10-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

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

Absolutely nothing.  The application did not have focus and was not being used directly at the time of the crash.

Prior to the crash, I had loaded a PNG screen shot, cropped it and saved it to a new file.  I then switched applications and the crash occurred a few minutes later.

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