[trojita] Some messages not displayed?

[Wim Lewis]

This may be PEBKAC, but I've noticed that some messages in a particular 
mailbox simply don't appear in Trojita. Other messages before and after the 
affected one(s) are visible. The situation:

 - largish mailbox being served by uw-imapd (I know, I know)
 - message doesn't appear in trojita, but does appear in mutt talking to 
the same imapd
 - nothing obviously unusual about the message's formatting in the mailbox 
file


Any thoughts? Is there something I can do to debug this?
