Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-59-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
When using the IntelliJ IDE, opening a large XML file (~16MB) with syntax highlighting enabled and then copying it to the clipboard (Ctrl+C), Plasma crashes.
After restarting Plasma, when opening the menu/history of the Clipboard widget it crashes again.

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".
