-- Information about the crash:
- What I was doing when the application crashed:
One behaviour:
After logon applications from previous session are starting (System Monitor, Dolphin, Firefox and announcements (above clock)),
desktop wallpaper is shown partly and when all program is loaded the screen become black,
after this I don't see KDE taks bar
and I can use started programs.

Second behaviour:
Similar as above, but when after logon instantly I want to show menu by pressing 'Super' key
screen freezes and computer does not responds.

-- Backtrace:
Application: Plazma (plasmashell), signal: Aborted
