Description sroub 2017-10-12 08:30:29 UTC

Application: plasmashell (5.8.7)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.87-25-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:

Typical this happens when I use Matlab and have many matlab figures opened. After typing "close all" in Matlab, all figures close but then the plasma crashes. This behaviour is not 100% reproducible.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
