Sentry Crash Report:

Description Alex 2015-06-29 15:14:38 UTC 
I pressed meta+tab by error and I can't access all my windows: they are open "somewhere" but I can't see them and I don't know how to reach them.

I have no virtual desktop configureds and no activities, just my two monitors on a single destop.

Using Kubuntu updated packages from repository backports

I had to trim down the bug report because it was > 64K and even drkonqi crashed 

Reproducible: Always

Steps to Reproduce:
1. press meta-tab 3 times
2. get an empty desktop and drkonqi handling the crash
3.



Application: plasmashell (5.3.1)
