Application: plasmashell (5.8.7)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.90-28-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
It seems that the changing menus of Kontact don't work correctly with the global application menu bar. The menus that get removed when switching to a different module of Kontact remain visible in the menu bar. When selecting one of the non-current menus, Plasma crashes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
