Application: skanlite (1.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed: I opened the Scanlite. Without changing anything, I press the button "scan". Then the program dissapears and gets on the crash dialog. I am using Ubuntu 13.10 64bit (just upgraded to it).

The crash can be reproduced every time.

-- Backtrace:
Application: Skanlite (skanlite), signal: Segmentation fault
