Sentry Crash Report:

Description Bernhard Lindner 2015-10-11 20:43:25 UTC 
Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-30-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:

I was simply opening the application menu (not K-Menu; the alternative one called "Anwendungsmenü" in german Kubuntu) and searching for some application there. 

The issue is pretty easy to reproduce. Just quickly move the mouse cursor above the opened application menu in circles for some time. The continuous opening and closing of sub-menu panels leads to a crash sooner or later.

The crash can be reproduced every time.

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