Occurs the same, Gtk.Notebook is catching the "button-press-event" over conversation.tab_label. I have just read gtknotebook.c in order to see how was treating "button-press-event" signal, and is comparing x,y coords. If you click in a place corresponding to tab coordinates, will focus the tab. The problem is that you have a toplevel widget catching this signal. If there is something invalidate that we are done.
