Description peter flexer 2015-05-03 17:50:05 UTC
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I was changing the Desktop effects settings. It happens during work, browsing etc, even during times where I dont use the Task manager (i.e. while using Firefox). I use fglrx graphics drivers, before that I used radeon but it too crashed often.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

This is not a native Kubuntu install, but Ubuntu with Kde 4 installed afterwards, then upgraded to Plasma5 via Ubuntu's update manager.

Comment 6 David Edmundson 2015-05-03 21:48:49 UTC
Backtrace shows the task manager changing, resutling in QtQuick doing something odd and crashing.

The task manager might be changing due to a different reason in your case, but these traces still line up as being the same bug.

Hy
Thanks a lot for the explanation!
