Bug ID: 403727
Summary: Bug when changed wifi
Product: plasmashell
Version: 5.12.7
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: arberarc...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.12.7)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-43-generic x86_64
Distribution: Ubuntu 18.04.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
There were two saved wifi networks that I could connect. I was already
connected to one of them. Then I decided to change the network that I'm
connected. I clicked the wifi symbol on the tray, clicked 'Connect' button of a
different wifi entry.
- Unusual behavior I noticed:
The bottom panel (the only panel I have, I don't know its name, it's like the
panel of the Windows) disappeared and bug report software opened automatically.
Then the panel reappeared.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
