The attachment show Kmail (kdepim-4.4.2-1.fc12.x86_64) accessing an email from dovecot over imap.
From the wireshark-imap-trace.txt you can see at line 77 that the headers do not end cleanly "X-)". And at line 84 there is text from the headers that is not part of the body "-Spambayes-Trained: ham".
The email being access by dovecot is in: 1272011889.M384349P30156.f12barry.office.onelan.co.uk,S=6494,W=6606:2,S
Because of this bug kmail fails to show the message cleanly on screen.
