Description Pavlo Verba 2018-10-08 14:25:11 UTC 
Application: plasmashell (5.13.5)

Qt Version: 5.11.2
Frameworks Version: 5.50.0
Operating System: Linux 4.18.9-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Used 'xinput disable 13' from Konsole, which stands for the TrackPoint on my laptop.
Using it this device crashes Plasma most of the time, but using it on other devices doesn't.

The crash can be reproduced every time.

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

This means Qt is quitting, this happens on result of an X error.

It then crashes in plasma code but that's after it's exiting anyway

No new duplicates in over two years. Assuming it's been fixed not, or else we'd have gotten more reports.
