James,

You're right, I was in single variation mode.  What a weird bug that
multivariation does not pick up the easy mate in one and opts for a bad move.  I
still love the Gandalf engine, and I usually use singe variation mode, so this
does not bother me so much.  You can probably find weird bugs like this if you
look hard enough in a lot of engines.  I'm sure Steen will fix it when he has
time to put out a patch.
