Bug 491942

Application: skanlite (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 5.14.21-150500.55.73-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.5"
DrKonqi: 5.27.9 [KCrashBackend]

-- Information about the crash:
I attempted to scan a page on my epson SX215 PSC as it was printing. There was a delay before a message box appeared with the message "I/O error".
This occured on all attempts until I closed Skanlite and restarted it.

The crash can be reproduced every time.

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