The panel that borders the top of the screen gives:
_NET_WM_STRUT_PARTIAL(CARDINAL) = 0, 0, 24, 0, 0, 0, 0, 0, 0, 1023, 0, 0
_NET_WM_STRUT(CARDINAL) = 0, 0, 24, 0

And the panel that is just below it gives:
_NET_WM_STRUT_PARTIAL(CARDINAL) = 0, 0, 51, 0, 0, 0, 0, 0, 0, 1023, 0, 0
_NET_WM_STRUT(CARDINAL) = 0, 0, 51, 0

So there are two separate struts and one is completely in the other.

Yea, it didn't occur to me at first that struts are always specified
to be from the edge of the screen.   I was thinking that struts had
offsets and somewhere the offsets were a pixel off.

Maybe handling the one strut is completely inside another strut case
would be good enough?

Although I suppose it's conceivable that if someone had a vertical,
full-height, auto-hide side panel (from a program other than
gnome-panel) in addition to a standard horizontal gnome panel that
things would still be broken.
