Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.0-36-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

-- Information about the crash:
I was just clicking away in chromium, which was running in full screen with only one panel and obviously the browser's window title the only other elements visible during the crash. I've not observed any adverse or otherwise unusual behaviour before, during or after the crash.

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