This is not reproducible, and I didn't see an error with similar code
(with different data) in a fresh session. Are you sure this is all you
did? Didn't you have a call to trellis.par.set / lset somewhere in
between?

There is a bug involved, and it has already been reported, and a
workaround posted. I'll upload a new version of lattice which fixes this
in a couple of days.
