You may be able to get away with the "clicked" signal or perhaps the "button_press_event" for the 
GtkLabel/GTkWidget that is used for the header.  The problem with this is, what happens if the tabs are 
changed via the keyboard. - You would also then have to use "key_press_event" and it all just looks messy 
then.

If the switch-page doesn't work, try "change-current-page", I think that's the signal I use.  There is always 
"select-page" too.  See the docs for more info (this area of the documentation really needs improving):
