emacs 23 conversion - headers fail

[Charles Petrie]

I’m going from a previous version to 23. The conversion to mbox seems
fine. Except: no headers will display. Instead there is an error message
that ‘ Search failed: “ “ ‘ A lot of other stuff doesn’t work as well,
but this is critical. Any clues please?

Thanks,
 Charles Petrie
