Bug 304727

Application: skanlite (0.7)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Sitting back in my chair relaxing; in other words, nothing (Firefox and LibreOffice are running, but iconified).

I have an HP Deskjet 1050 PSC, using the following driver:  HP Deskjet 1050 j410 Series, hpcups 3.12.2 (color, 2-sided printing)

The crash can be reproduced every time.

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