Bug ID: 365052
Summary: plasma crashed after removing panel due to widgets
dissapearing while still showing as loaded
Product: plasmashell
Version: 5.5.5
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: scdnew...@outlook.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.5)
Qt Version: 5.5.1
Operating System: Linux 4.1.26-21-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"
-- Information about the crash:
- What I was doing when the application crashed:
- Unusual behavior I noticed:
Cpu widget dissapeared when moving towards the top of screen or top panel. I
added cpu widget again and again it vanished after moving it towards top panel,
I tried again and the widget vanished, i then noticed that 3 cpu widgets where
showing as loaded but not visible on the desktop. I removed the top panel and
noticed one of the cpu widgets was on a top panel under the one i removed. I
didnt create 2 panels so it must have jumped there somehow. It was then plasma
crashed. Yet still widgets were showing to cpu widgets were loaded byut yet
none visible on the desktop or either any panel. I removed all visible panels
then check widgets and all cpu widgets where now unloaded
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
