Which version are you using?  I thought I already fixed this bug
recently, but on second thought, I may have forgotten an essential
step.  (Phil's suggestion is correct, but the current code is supposed
to do this for you.)

You can fix this by defining the rigid bodies yourself - the default
behavior is to automatically make each chain a rigid group, but since
we can't assume unique chain IDs, the code will use residue ranges as
well.  (This is new in the nightly builds; previously the entire
structure was treated as a single group.)
