Description S Egbert 2025-08-06 00:29:39 UTC

Application: skanpage (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-37-amd64 x86_64
Windowing System: Wayland
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
When accidentially hitting refresh button because I was thinking it was for display refresh, not refresh list of printer devices.

I noticed that the connected printer device is no longer on the list, and I WANT THIS ORIGINAL printer; so I proceed to EXIT from window title bar and restart the app (which gives me back my original printer device).

Using Brothers MFC-L2690DW over IP address.

Well, each time, it crashes.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Skanpage (skanpage), signal: Segmentation fault
