Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic-pae i686
Distribution: Ubuntu 11.10

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

tried to scan via DIGIKAM with an Epson Perfection 2450 scanner which, anyway, IMAGESCAN does not succeed to contact (even if it's recognized by the system).

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
