I found a reference to this on the gtk-list using google: 
http://mail.gnome.org/archives/gtk-list/1999-October/msg00380.html

The suggested workaround is to connect to the 'hide' method of the
popup, which works just fine in my brief testing.

cb.popwin.signal_connect('hide')  do
  $selected_item=cb.entry.get_text
  print "You have selected ",$selected_item,"\n"
end
