This is the problem that should have been fixed by the addition of the 
function KJanusWidget::removePage(), specifically by the call to 
removeWidget(). It fixed (what I believe is an) identical problem for my 
application. Could you please check whether the code posted in
  http://lists.kde.org/?l=kde-core-devel&m=103678273823118&w=2
crashes for you too?

I believe that this is actually a Qt problem. Reverting back to an old version 
of QWidgetStack (prior to the new event filter stuff) makes everything work 
fine for me. I filed a bug report; after a little discussion, the bug was 
assigned very low priority as the removePage() function provided a workaround 
and as I could not come up with a pure Qt example that crashed.
