Problems with mixed encoding

One of the posters to a NG I monitor uses Turnpike (a no-longer updated 
email client and newsreader.) Turnpike marks all outgoing news posts as 
mime encoded (in the header), but uses uuencode for images (so marked in 
the body of the message). The result is that TB treats the image file as 
a text file. From other posters' replies, it appears that TB cannot 
witch decoding mode when part of a message is encoded differently than 
the message header shows. I think that's a bug. Can it be fixed?

Please don't refer to me to the bug-report site, it's a PITA to use.
