Qt Version: 5.15.3
Frameworks Version: 5.93.0

-- Information about the crash:
- What I was doing when the application crashed:
One-or-two-selections-300dpi-colors:
  1. I clicked "Scan"
  2. The scanner makes its first slow move to actually catch the selection.
  3. It makes its second faster move to go back to its initial postion...
  4. ... and skanlite used to show the scan result during this second move but crashes at this moment.

One-selection-75dpi-colors:
  1. Idem.
  2. Idem.
  3. Idem...
  4. ...and skanlite doesn't crash but is stuck at 0% when loading the scan result

No-selection-300dpi-colors goes fine.

The crash can be reproduced every time.

-- Backtrace:
Application: Skanlite (skanlite), signal: Aborted
