Well, it's a little more logical if you look at it from the other side: 
Tab always focuses the next control in the navigation sequence, unless
the currently-focused control swallows Tab for its own purpose, in which
case you have to use Ctrl+Tab.

The GtkNotebook fits into that model too: the proposal states that Tab
should cycle you through the controls on the frontmost page, and
[Shift+]Ctrl+Tab should take you out of the notebook control
altogether.  Switching between tabs is actually supposed to be done by
Ctrl+PgUp and Ctrl+PgDn (or by left/right arrow keys followed by Enter)
when an actual page tab has focus).

Cheeri,
Calum.
