Description soee 2015-01-31 19:05:27 UTC

Since we have Plasma 5.2 packages in Kubuntu Vivid i decided to give activities a try.
I can create new activity without any problem but as soon as i switch to it, i can see only black screen. In previous version (5.1.95) i could fix it by starting plasmashell  from krunner - so the problem here is plasmashell not loading after changing an activity. Now in 5.2 if i try to start plasmashell manually i can see for a moment empty panel but after few seconds it is gone - so plasmashell won't start.

In 5.1.95 when i was able to start plasmashell on target activity and than switching back to previous one (activity) i had the same problem with black screen. So in general: i think the issue here is switching activity prevents plasmashell from loading/starting on it.

Reproducible: Always

Steps to Reproduce:
1. Create new activity
2. Switch to new activity

Actual Results:  
You can see only black screen (but for example krunner works)

Expected Results:  
Plasmashell should be started, we shoud see panels, wallpapers etc.

I forgot to mention:
Kubuntu 15.04 Alpha 2 (with latest updates)
Plasma 5.2
QT 5.3.2
Kernel 3.18.0-12

I can confirm this. 
Plasmashell dies. After restarting it, switching activities works as expected.

yes, I can confirm this bug.

Seems like during some updates it was somehow fixed. Closing it as it works for me now in Plasma 5.2.2.
