Bug ID: 361104
Summary: Plasma crashed after switching virtual desktop via
application shortcut and then switching back
Product: plasmashell
Version: 5.5.4
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: nik_1...@mail.ru
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.4)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-15-generic x86_64
Distribution: Ubuntu Xenial Xerus (development branch)
-- Information about the crash:
- What I was doing when the application crashed:
I have Thunderbird shortcut in my task manager.
I started it on virtual desktop 2.
While I was on virtual desktop 1 I clicked on that shortcut and desktop
switched to 2-nd to Thunderbird.
Then I immediately clicked on 1-st desktop in task manager.
Desktop had swithed but task manager freezes for about 1 second and crashes.
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
