Sentry Crash Report:

Description Eike Hein 2014-06-22 04:10:30 UTC 
I can reproducably crash plasmashell by slowly scrolling inside an application category (e.g. Internet) with the mouse wheel.

Qt is 5.3 branch.

ASSERT message:

plasmashell(3780)/default qt_assert: ASSERT: "!isEmpty()" in file /home/sho/devel/src/qt5/qtbase/include/QtCore/../../src/corelib/tools/qlist.h, line 298   

Backtrace:

Application: plasmashell (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
