Description Faustino Aguilar 2015-09-09 05:46:42 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I have read about many bug plasma 5, but this is not my problem.
My desktop was fine until I installed the latest version of GeoGebra. Maybe it's because I installed "java 8" and then geogebra installed "java 7". Then I uninstalled geogebra to solve the problem, but now plasma crash everytime that i turn on the pc.

To reproduce the crash:

- Install the latest geogebra from http://www.geogebra.org/download
- Open Geogebra
- Close Geogebra

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
