Bug 336340

When I log into the next session plasma crashes shortly after having (seemingly) loaded the desktop. I'm then thrown back to the login screen.

I'm using the neon Kf5 daily PPA

Reproducible: Always

Steps to Reproduce:
1. Log into the neon 5 session
2. Wait for it to finish loading
3. Crash 
Actual Results:  
It crashed

Expected Results:  
Should not have crashed 

Application: kdeinit5 (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
