Turns out that PHP's convert_uudecode() implementation is broken.   
Fixed in Horde_Mime 1.6.1.

FYI: It is possible that an IMAP server could refuse to serve that  
message since it contains an invalid MIME type (x-uuencode) - these  
servers appear to not be willing to send unknown content-encoding data  
in a bodystructure return.  Some servers are more lenient than others  
in what they serve, however, so it does work on some.  Dovecot 2.1  
will display the message, for example.
