Today's issue was that a couple of people reported the plasma panel had
locked up overnight. The clock was stuck at a bit after 9:00pm for one
person and a bit after 11:00pm for someone else.
I tried stracing plasmashell but there was no strace output, and strace
was locked up. I couldn't ^C out of it but a kill without -9 was able to
Restarting plasmashell fixed the panel problem.
Anyone else seen this sort of behaviour?
