Thanks.  I upgraded to -test74 (from source) and it's a big improvement.
  Using Thunderbird 1.0.2 and imap, I occasionally see this when
deleting a message:

Jun 28 12:22:04 mail dovecot: IMAP(epate): file mbox-sync-update.c: line
437 (mbox_sync_update_header_from): assertion failed: (ctx->mail.uid ==
0 || ctx->mail.uid == mail->uid)

It usually takes a couple of tries to get the message to delete. I also
see it when telling TB to mark the message as "Junk" or "Not Junk".

Thanks for your help,
