Plasma crashes when a program on one desktop focuses a window on another desktop, then the user quickly switches back to the initial desktop. You must wait about 10 seconds in order to avoid the crash.

Reproducible: Always

Steps to Reproduce:
1. Make sure the system has at least two desktops. Put your default web browser on one (I use Firefox) and your file manager on the other (I use Dolphin).

2. Create a shortcut file to a website or find one on your drive, then click it. You will automatically be taken to the other desktop as the web browser is focused.

3. Quickly use the pager to scroll back to the initial desktop, on which you have the file manager open. Ideally click on the background or various Plasma menus afterward.

Actual Results:  
plasmashell crashes and the KDE crash reporter pops up.


Several details which might be related to the problem: The crash occurs while I still have the bouncing icon on the cursor, as well as the task manager entry of the web browser showing the spinning cursor. I use the icon-only task manger on the default panel. I use the following KWin and Plasma themes:
