I've snagged a repeatable case and got a truss of the imap process.  I'm 
inclined to agree with you.

I'll report it to the Thunderbird ppl.

The sequence is (more or less) this:

Client: 10 UID fetch 90309 (BODYSTRUCTURE)

[imapd reads the whole message, then futzes with the dovecot.index file]

Imapd: * 6056 FETCH (BODYSTRUCTURE ("text" "plain" ("charset" 
"iso-8859-1") NIL
NIL "7bit" 796 22 NIL NIL NIL) UID 90309)
Imapd: 10 OK Fetch completed.

Client:11 UID fetch 90309 (UID RFC822.SIZE BODY[]<0.10240>)

[imapd read the whole file again - TWICE!]

Imapd: * 6056 FETCH (BODY[]<0> {2064}
        [entire message]
        UID 90309 RFC822.SIZE 2064)

[more index stuffing]

Imapd: 11 OK Fetch completed.

Client: 12 UID fetch 90309 (UID RFC822.SIZE BODY[]<10240.-8176>)

Imapd: 12 BAD Error in IMAP command UID: Invalid BODY[..] parameter: 
Missing '>'
 in '<10240.-8176>'
