Bug 387649

Application: plasmashell (5.8.7)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.92-31-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
Closed two konsole tabs (the last one closing that particular konsole window, the only konsole window on that particular virtual desktop), than switched virtual desktop.
All by keyboard strokes, in quick succession.
Plasma crashed instantly.

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