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) Qt Version: 5.4.1 Operating System: Linux 3.19.0-21-generic x86_64 Distribution: Ubuntu 15.04 -- Information about the crash: -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
