Bug ID: 454409
Summary: Skanlite crashes when it attempts to access my
scanner.
Product: Skanlite
Version: 22.04.1
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kare.s...@iki.fi
Reporter: beedellrokejulianlockh...@gmail.com
Target Milestone: ---
Application: skanlite (22.04.1)
Qt Version: 5.15.4
Frameworks Version: 5.94.0
Operating System: Linux 5.18.0-60.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (Rawhide Prerelease)
DrKonqi: 5.24.5 [KCrashBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I have been able to scan 2 times, but currently Skanlite is unable to preview
and reselect the device. I have not interacted with my printer since my 2nd
initialisation of Skanlite. This error occured during my 3rd and subsequent
initialisations.
- Custom settings of the application:
This occurred during my 3rd initialisation of Skanlite. The previous
initialisation did not retain what I configured during my 1st initialisation.
The 3rd initialisation retained the configuration of the 2nd initialisation.
Closure of Skanlite and subsequent disablement and enablement of my scanner has
remediated this problem: I was instructed to choose the device to utilise, I am
able to preview and scan, and Skanlite did not retain my previous
configuration.
The crash can be reproduced every time.
-- Backtrace:
Application: Skanlite (skanlite), signal: Segmentation fault
