Bug ID: 430737
Summary: crashed after deleting job because of unrecognized
location of the printer
Product: print-manager
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: dantt...@gmail.com
Reporter: prote...@hotmail.it
Target Milestone: ---
Application: kde-print-queue (20.12.0)
Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.4.0-58-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20
-- Information about the crash:
- What I was doing when the application crashed:
I was deleting a job because of unrecognized location of the MFC-L2700DW
printer. I've just changed the way the printer link to the router to fix this
issue. Implicitclass driver looks like to have problems.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Coda di stampa (kde-print-queue), signal: Segmentation fault
