Sentry Crash Report:

Description George Diamantopoulos 2016-11-26 02:12:05 UTC 
Application: plasmashell (5.8.4)
 (Compiled from sources)
Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.8.10-gentoo x86_64
Distribution: "Gentoo Base System release 2.3"

-- Information about the crash:
I was typing a search string into K menu. Plasma crashes 99% of the time when I do that. It also crashes when the search is performed in Plasma search widget (Alt+F2).

This behaviour has been manifesting for quite some time (several months), but only now have I decided it was annoying enough to recompile everything with debugging symbols and issue this report.

The crash can be reproduced every time.

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