Public bug reported: After upgrading to Kubuntu 16.04, my plasmashell is acting up badly. After startup it sometimes (but not always) freezes for long periods before becoming responsive again. Today, I found just plasmashell reporting over 100% CPU usage for several minutes, although it was responsive (albeit slowly) during that time. It seemed to drop back down to almost nothing entirely on its own, despite no change in what I was doing.
At the recommendation of someone in the #KDE IRC channel, I grabbed the attached backtrace using gdb. The person I spoke to indicated that it seemed to be waiting on a lock indefinitely.
