Application: skanlite (0.7)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:  I was using scanner Genius-ColorPageVivid1200XE, scanning document
  
- Unusual behavior I noticed: escaneament went to the 9% and then started again

- Custom settings of the application: scanning in black and white, with the maximum allowed resolution (12 bits and 600 pixels)

The crash can be reproduced some of the time.

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