Sentry Crash Report:

Description Abyss 2016-12-19 10:55:40 UTC 
After login to KDE session I can see only black screen. When I run plasmashell manually (via 'kstart5 plasmashell') it loads successfully and shows in tray an icon of Crash Assistant, which says that previous plasmashell has crashed.

I use auto-login - don't know if it matters.

Also Crash Assistant says that backtrace is not informative.
Comment 1 Marco Martin 2016-12-19 12:26:00 UTC 
if drkonqui is showing up, can a backtrace with debug symbols be produced?
Comment 2 Abyss 2017-01-02 12:51:27 UTC 
Application: Plasma (plasmashell), signal: Segmentation fault
