This is almost certainly related to http://tinyurl.com/5pmbf .  If you 
look through that thread you will understand the issues, and see that I 
had checked in a partial fix for a different problem a few days ago that 
caused some other problems in turn.  Now there's what should be a fix in 
the CVS.  Please let me know if that's not the case.
