Bug ID: 382411
Summary: Plasmashell crashes intermittently
Product: plasmashell
Version: 5.10.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
Application: plasmashell (5.10.3)
Qt Version: 5.9.0
Frameworks Version: 5.35.0
Operating System: Linux 4.12.0-1-MANJARO x86_64
Distribution: "Manjaro Linux"
-- Information about the crash:
- What I was doing when the application crashed:
Usual desktop activities - browsing the web in Firefox, reading some PDFs in
Okular, modelling in Blender (these applications are normally always open) -
the activity in particuar doesn't seem to affect when it happens, seems to be
at random
- Unusual behavior I noticed:
Plasmashell crashes at random, taking with it the taskbar, application
titlebars, redshift screen state etc, but krunner still works, alt-tab still
works. It used to be less of an annoyance as it would normally just
automatically relaunch after less than a second, though lately after the last
few releases it seems to be less able to do this. Now I am often left without
it and sometimes I am able to recover it by runnning "kquitapp5 plasmashell"
followed by "kstart plasmashell", but on other occasions the shell will start
but the taskbar is full of unidentified X apps that I am unable to switch to
and the only way to recover seems to be restarting SDDM to get a new X session.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
