Description Antonio Rojas 2015-11-22 11:05:05 UTC 
Plasma crashes when deleting an entry in Recent Documents in kickoff. Removing the same entry in kicker works fine. Happens for every entry, even after wiping the kactivities database.

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