Sentry Crash Report:

Description kde 2017-08-08 15:08:18 UTC 
Application: plasmashell (5.9.5)

Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.11.12-200.fc25.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

Matlab had encountered a problem and needed to close. After confirming the Matlab crash and selecting "End now" (in matlab), the matlab windows were closed. At this point Plasma crashed too.
The bug has already happened, but since I don't know why Matlab crashed I cannot reproduce it willingly.

The crash can be reproduced sometimes.

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