unless i've lost my mind and i'm remember things wrong i recall a discussion
about this a few weeks (months) back that was basically resolved as that
signal is not emited by gtk+. that is they have and document the signal, but
nowhere in all of the gtk+ (c code) do the emit it. you may be able to look
back over the mailing list archives to find the thread but i don't know if
anyone ever posted a workaround. if anyone knows of anything this seems to be
a good entry for the faq. there will probably be something about the problem
in there, it would be nice to have something about a work-around. please share
if you got one...
