Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

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

1 - click the K-button for the application menu (the launcher based on cascading popup menus) to appear
2 - rapidly move your mouse pointer in order to hover categories & their items , keep hovering jumping from one cat-item to another cat.
(it takes no more than some seconds to trigger the crash everytime)
3 - the whole bottom panel will crash and restart quickly after

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
