I confess to running 1.0.0, which apparently lacks this bit of housekeeping.

At the moment I have no messages in my Trash folder (so there are no 
files in ~/Maildir/.Trash/cur) and ~Maildir/.Trash/dovecot-uidlist 
has 10273 lines, and the first messages listed are nowhere to be 
found anywhere under Maildir. A quick scan of Maildir shows that of 
14 logical folders including the inbox, 6 have dovecot-uidlist files 
whose linecount is greater than the number of files in cur plus one.

Looking at which directories have oversized dovecot-uidlist files, it 
seems like they are the ones that do not get direct deliveries of new 
mail but only receive messages by an IMAP client shuffling messages 
around.
