------- Comment #3 from Kevin Ryde  2009-01-15 21:51 UTC -------
muppet points out an original motivation for trapping in signal handlers was
that it's not possible to jump out of a main loop from a signal handler without
leaving glib in a terrible state.  I think that may apply to these AboutButton
and LinkButton callbacks, ie. that they're run out of signal handlers.

LinkButton runs the uri hook out of its class handler for the "clicked" signal.
 AboutButton runs its url hook out of a signal connected on the "activate"
signal of a button widget (a LinkButton as it happens).  The AboutButton email
hook runs from somewhere deep in TextView "follow" business, though presumably
it usually gets there from either a button_press_event or key_press_event
handler somewhere far up the chain.
