Application: plasmashell (5.4.2)

Qt Version: 5.4.2
Operating System: Linux 4.2.0-30-generic x86_64
Distribution: Ubuntu 15.10

-- Information about the crash:
Sometime, when I launch applications from fhe "start" of KDE (I don't know the english traslation, in italian in is "Digita per cercare.." may be something like to "Type to search.."), Plasma crashes; but If I try to launch again the app in the same way, Plasma lauch the app flawless.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
