the maestro3 snapshot in 2.4.2pre2 is not up to date.  I imagine it came
from alan, who got the jan30 patch, but didn't get the trivial feb 04
patch that fixes the oops you're seeing.

the proper patch to 2.4.2-pre2 (and 2.4ac-current, presumably)
is attached.  Does it fix you problem?  [it tries to do so without
duplicating code, you'll notice.]

I'd rather do this in a seperate patch that does lots of other cleanups
that are pending.
