Plasmashell crashes reliably when I change the system tray settings in whether to show or not show an entry (tested with Owncloud, Nextcloud and "Audio volume" across two laptops - one with a brand new profile).

Steps to reproduce:
1) Go into System tray settings => entries
2) change Audio Volume to "hidden" or "shown" and click "OK" (not apply)
 (if it was on auto it does not crash now, only if changed from hidden or show)
3)Open settings again and change it to the opposite (hidden/shown)


Here is a crash report which I'm told is low quality by the crash handler, but it might provide a hint. (It installed all the debug packages that the crash handler wanted ).


Application: Plasma (plasmashell), signal: Segmentation fault
