Bug 449252

Application: skanlite (21.12.1)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.16.1-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Uruchomiłem progrm skanlite. kliknąłem opcję Podgląd. Po ukazaniu się skanowanej strony okienku podglądu skasowałem zaznaczenia i kliknąłem opsję Skanuj. Program zaczął skanowaś i chwilę później zniknł z ekranu, natomiast pojawił się Pomocnik zgłaszania usterki.
Próbowałem skanować z zaznaczeniem całej strony i bez zaznaczania obszaru skanowania. Za każdym razem było to samo.

The crash can be reproduced every time.

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