Sentry Crash Report:

Description Florian 2017-03-15 15:34:53 UTC 
Application: plasmashell (5.8.5)
 (Compiled from sources)
Qt Version: 5.6.2
Frameworks Version: 5.29.0
Operating System: Linux 4.4.26-potatOS x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- Requirements for reproducing
-> Get an application that only creates an "audio-socket" when its playing audio (Pidgins Notification-Sounds in my case)
-> Get a second audio output device (bluetooth in my case)

- What I was doing when the application crashed:
Pidgin plays a sound when I get a new message. It removes the application from the playing-list, once its done. When i drag and drop this application to a different device, and the "application" disappears while being dragged, plasma hangs for a few secs and then segfaults.

- Custom settings of the application:
As stated above, you need a second audio device to drag the application to.

The crash can be reproduced every time.

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