snapshot before chrashing

Can you get a backtrace? You'll have to install debug symbols. Thanks!

Actually, it doesn't get caught by kcrash. It just dies. I tried starting from konsole and got the following line when it died:
ASSERT failure in QList<T>::at: "index out of range", file /usr/include/qt4/QtCore/qlist.h, line 393

Confirmed.

fixed in trunk with r835199 and in the 4.1-branch with r835200.
see also bug #155196

that the top-level "More" menuitem jumps after clicking an item from the bottom-position to a position in the middle (or to be more exact all items displayed after it are not corrected cleared within the top-level menu) is another issue and not a regression of the commit above ;)

Thanks for the feedback!
