-- Information about the crash:
When editing the entries in the system tray settings I was disabling the notifications on the monitors that I do not want them to be displayed on (I have 3 monitors). When disabling notifications and then clicking OK on the dialog box the dialog box will close and then plasma will crash. 

One other odd behavior I noticed that may or may not be relevant. I have 3 monitors and the monitor I have ordered as the primary monitor is not the monitor that gets the default panel on it, the notifications and the panel stay in my leftmost monitor which is why I was disabling notifications on that monitor.

Steps to reproduce:

1. Click the down arrow to open the system tray on the default panel.
2. Click Entries
3. Scroll to notifications
4. Click the drop-down an select "Disabled"
5. Click OK

Plasma shell will crash immediately after this.
It also crashes if you take the same steps above but in step 4 instead choose "Shown when relevant" if it's disabled.

The crash can be reproduced every time.

I realize I made one minor mistake in my reproduction steps, after step 2 there needs to be an additional step to click on the icon on the top of the panel that opens that says "Configure System Tray..."

Thank you for the bug report! This issue is already being tracked in another report, so I'm merging the two.
