This looks like the real culprit to me.

Unfortunately your Qt has no debug symbols (reconfigure Qt with '-debug' to 
get them) so there are no exact line numbers available.

Could you re-send the initial problem to kde-core-devel? I think more people 
who really know the kdeui/qt internals read that list.

Sounds like a problem in the Qt layouting code or in QWidgetStack to me, but 
that's my first guess.
