Sentry Crash Report:

Description a.mccullough 2016-01-12 21:41:30 UTC 
Application: plasmashell (5.5.2)

Qt Version: 5.5.1
Operating System: Linux 4.3.3-5-default x86_64
Distribution: "openSUSE Tumbleweed (20160110) (x86_64)"

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

Opened activity switcher using keyboard 
Open preferences dialog for an activity
Dialog opens
Release activity switcher keys
Activity Switcher closes, and crash happens.

This happens every time I open a dialog from the activity switcher ONLY when I use the keyboard to open the activity switcher. Opening it from the toolbox in the top left corner doesn't make this happen as focus is forced onto the dialog and makes it impossible to close the activity switcher.

The crash can be reproduced every time.

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