Description Matt Spaulding 2015-01-19 20:55:07 UTC 
Every time I log out of KDE the screen goes black and stays there.  The cursor is still visible and can be moved.  From the backtrace of plasmashell it looks like a crash occurs and then plasmashell hangs in the crash handler instead of exiting.

Reproducible: Always

Steps to Reproduce:
1. Exit KDE by choosing the logout option.
2.
3.

Actual Results:  
A black screen appears and the login screen never appears.

Expected Results:  
Logout proceeds and the display manager login screen appears.

Comment 1 soee 2015-01-23 22:38:38 UTC 
I can confirm this bug on Kubuntu Vivid and Plasma 5.1.95.
Comment 2 Martin Klapetek 2015-06-22 08:44:31 UTC 
Is this still happening with Plasma 5.2/newer?
Comment 3 soee 2015-06-25 11:42:16 UTC 
Works fine on my laptop (Kubuntu 15.04 Plasma 5.3 / pre Kubuntu 15.10 Plasma 5.3 ) but logout ends with black screen on desktop (Kubuntu 15.04 + Plasma 5.3).
Comment 4 Hemant Kumar 2015-07-11 13:23:58 UTC 
It seems to be happening again. I am on latest : Archlinux Plasma 5.3.2:

Comment 5 Martin Klapetek 2015-07-12 10:41:04 UTC 
The last crash in particular was fixed last week. Unfortunately it will make it only into Plasma 5.4 release.

I'll close this here, if you get another crashes at logout/plasma quit, please open new reports (unless the backtrace is identical to any in this report).

Thanks
