Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-25-generic x86_64
Distribution: Ubuntu Yakkety Yak (development branch)

-- Information about the crash:
I was dragging and dropping some text into terminator and both plasma and terminator crashed. The terminator crashes happen somewhat frequently when doing a drag and  drop.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
