That seems to ring a bell: I remember a thread on the gtk devel ml where
somebody complained that mouse motion events were swallowed by the 
scrollbars
of a scrollview widget. Someone replied that this is an immanent problem
with gtk2 because some widgets (scrollbars, textviews and others I don't
remember) are rendered into own windows that have an independant event 
queue
so that the parent widget cannot catch the events for the child widget.
So I'm afraid it's very likely that the button events of the text widget
in your example are not accessible for the tree widget. A possible solution
would be to catch the events in the text widget.
