Bug 458517

Application: skanlite (21.12.3)

Qt Version: 5.15.4
Frameworks Version: 5.97.0
Operating System: Linux 5.18.0-4-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux bookworm/sid
DrKonqi: 5.25.4 [KCrashBackend]

-- Information about the crash:
Scanner one page. Had to click on "feeder is out of documents" message TWICE.
Then, scanner would not work. So I clicked Reselect scanner device and app crashed.

The reporter is unsure if this crash is reproducible.

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