I run 6 desktops in my fully updated(01-06-16) Kubuntu 15.10 system, dual-monitor system. I upgraded from 14.10(which was out of support) to 15.04 right to 15.10.

When I empty the trash on say Desktop 2, I lose my bottom Task Manager bar on all desktops except for Desktop 2.

This has to be a bug and is super annoying. The only way to fix, beyond rebooting is to re-run

plasmashell

from a konsole window

I also try to quit plasmashell using this command

kquitapp5 plasmashell && plasmashell

Please help. I've been using Kubuntu as my desktop since I discovered the Ubuntu family in 2005.

Thanks.
