Application: plasmashell (5.5.2)

Qt Version: 5.6.0
Operating System: Linux 4.4.0-desktop-1.mga6 i686
Distribution: "Mageia 6"

-- Information about the crash:
I installed Mageia 6 Cauldron in VirtualBox, and today Plasma crashes pretty frequently when using rpmdrake. Not sure this is related, though.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/i686/libthread_db.so.1".
