Application: plasmashell (5.8.6)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.57-18.3-default x86_64
Distribution: "openSUSE Leap 42.2"

-- Information about the crash:
- What I was doing when the application crashed:
automatic restart of plasma.  had just closed a file in Ocular.

- Unusual behavior I noticed:
Panel pops up when focus moves to a different window, does not hide until mouse-over.  Reported also in https://bugs.kde.org/show_bug.cgi?id=378037

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
