I was trying to report via the crash-reporting system. The backtrace was produced (see below). But the login button for kde-bug-reporting system was unfocused - so I could not report that way. Therefore you get the report here.

Reproducible: Sometimes

Steps to Reproduce:
1. Close lid on laptop
2. Open lid - to wake up
3.

Actual Results:  
Plasma crashes. 

Expected Results:  
Normal plasma wake up.

Application: plasmashell (plasmashell), signal: Segmentation fault
