Posting here for those who missed it in #plasma: this change makes plasmashell 
crash if kactivitymanagerd is running (because KScreen isn't done yet and yet 
kamd tries to access screenForContainment). The fault lies in 
kactivitymanagerd: I tried to look at the code but I couldn't find anything 
obvious.

Can someone more knowledgeable have an insight of why this happens?

This is the bt:
