Bug ID: 413909
Summary: Plasmashell crashes when I try to print something
Product: plasmashell
Version: 5.17.2
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: m...@florian-schulte.net
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.17.2)
Qt Version: 5.13.1
Frameworks Version: 5.63.0
Operating System: Linux 4.15.0-66-generic x86_64
Distribution: KDE neon User Edition 5.17
-- Information about the crash:
- What I was doing when the application crashed:
I printed some PDF using google chrome (but also happens from other
applications), then the task bars disappeared.
If I restart plasmashell manually (I use yakuake which survives and can still
be opened using a hotkey), but it crashes immediately again as long as the
printer is printing. When it has finished, plasmashell can be restarted
normally.
So i guess it could have something to do with the printer applet. I also have a
three-monitor setup with a default task bar on each screen. I don't know how it
is solved technically, but maybe there are multiple instances of the printing
applet running which could cause problems. But that would be just a lucky
guess.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
