Bug Description

This concerns libqtgui4 4:4.7.4-0ubuntu8 in Ubuntu Oneiric.

While using VirtualBox (i.e. virtualbox-qt), I encountered a program hang (on performing a snapshot-restore operation). I traced this down in a debugger to the QTreeWidgetItemPrivate::propagateDisabled() method in qt4-x11/src/gui/itemviews/qtreewidget.cpp:1643.

So far as I can tell, the widgets must be linked in a circular manner, because the tree propagation implemented in this method goes on forever. (Memory consumption does not increase.)
