Plasma 5.8 - plasma-pa/plasmashell crashes at logout

hamelg · 2016-10-09 19:46:53

I've just upgraded to plasma 5.8.
I have created a new user to check with a vanilla profile.
When kde session terminates these processes stay alive :

plasmashell & powerdevil wait a CONT signal to terminate (T state) !!?
If I send the CONT signal to these two processes , systemd exits gracefully.

I'm alone to encounter this issue ?

I 'm understand. Plasmashell crashes at logout. Drkonqui detects the crash and sends sigSTOP to plasmashell.

plasma-pa crashes plasmashell. Here is the backtrace :
