Application: plasmashell (5.12.6)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-39-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
- To reproduce:
 1. Open system tray settings
 2. Select the "Entries" tab on the left
 3. Change the visiblity of "Battery and Brightness"
 4. Click "Okay".

At this point, the desktop background goes black and the panel at the top disappears.  They both return to normal after a moment.

Effects of different visibility changes:
  "Auto" to "Shown": Crashes
  "Shown" to "Auto": Crashes
  "Hidden" to "Auto": No crash
  "Auto" to "Hidden": No crash
  "Hidden" to "Shown": Crashes
  "Shown" to "Hidden": Crashes

The cases which don't crash are the ones where the actual visibility of the icon doesn't change.  At the time of testing, Auto means that the icon is hidden.

Clicking the "Apply" button instead of "Okay" in step 4 occasionally causes a crash, but only rarely.
