ERROR: Error in source file:not well-formed (invalid token)

Howdy folks,

I'm hoping to upgrade a site of ours which is producing this error:
        ERROR: Error in source file:not well-formed (invalid token)

But when I did a search for it I found that both early Back-End and some
phpSlash sites came up with this error in google.  

I had thought that this was a server issue, but since there's a lot of
phpSlash sites with the error, it occurs to me that it was a bug which
was found & fixed at some point.

If anyone has run into this and knows the context I'd be interested.

Mike
