Hmm, interesting. You get this itemHeight call with item value 8.
I tried setting a breakpoint first at UMLListView::closeDatatypesFolder() and
then at QTreeViewPrivate::itemHeight(), and the item values I see are in the
range 0 to 7 but not 8.

For reference, here is the typical backtrace that I get:

I guess the difference could also be caused by the different qt/kdelibs version
that I am using.
I'll try again with updated qt and kdelibs but this may take a few days.
Did you build qt and kdelibs from source, too?
