Bug ID: 362674
Summary: Crash after monitors awakened.
Product: plasmashell
Version: 5.5.5
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: thebit...@earthlink.net
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.5)
(Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.6-gentoo x86_64
Distribution (Platform): Gentoo Packages
-- Information about the crash:
- What I was doing when the application crashed:
Right click in background where panel used to be.
- Unusual behavior I noticed:
When the screens awakend the panel was missing. Theis happens a lot. Sometimes
the panel moves from the bottom of the right screen to the bottom of the left
screen. It almost always is on the left (wrong) screen when booting from power
off state. Log out and login usually makes it apper on the right (correct)
screen.
While I was entering this information the kterm on the left screen crashed for
no reason. Then I got several kdeinit5 crashes about 1 minute apart. Sometime
during all this the panel reappeared ath the bottom the right screen where it
belongs.
- Custom settings of the application:
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
