Messages with charset UTF-8 and PGP data in the text/plain body don't  
seem to be displayable.

When such a message is clicked on, instead of the PGP passphrase  
prompt, we see this message:

"This message was written in a character set (UTF-8) other than your  
own. If it is not displayed correctly, click here to open it in a new  
window."

It works fine if the charset is US-ASCII.

I tried editing the mail files on the IMAP server and changing the  
Content-type header, but that didn't seem to make any difference  
within IMP. Clicking Message Source shows the edited message with the  
new Content-type header, but IMP continues to emit the above message  
about UTF-8 charset. I don't understand why this happens.

Clicking on the link in the message doesn't start the decryption  
process for the message, but simply shows the encrypted message in a  
new window.
