We have a suspected bug in GHC that causes this error randomly.  Due to the 
lack of a repeatable test case, we haven't made any progress on tracking it 
down.  If anyone can repeat it, we'd love to hear about it.

There are other things that can cause the above error message: e.g. old or 
corrupt interface files, as the message says, so the above instance might 
not be "the bug", I just thought I'd mention it in case you've ruled out 
other causes.

Cheers,
