Bug ID: 359671
Summary: Plasmashell crash on activity change
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: ctam...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.4)
Qt Version: 5.5.1
Operating System: Linux 4.2.0-27-generic x86_64
Distribution: Ubuntu 15.10
-- Information about the crash:
- What I was doing when the application crashed:
I change to the previous activity using a custom global keyboard shortcut.
- Custom settings of the application:
I used the Alt + Ctrl + Down Arrow as a shortcut to navigate to the previous
activity.
My shortcut to navigate to the next activity is Alt + Ctrl + Up Arrow and works
as expected. The crash happens everey time.
As a side note. I don't know if it is related to the reported problem but I
just found out that I am not able to access the Activities module from System
Settings
The crash can be reproduced every time.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
