[Dovecot] file name missing component in error message

[Mike Abbott]

Hi, we occasionally see this error message from  
maildir_mail_set_cache_corrupted():  "Maildir filename has wrong W  
value: %s/%s" but the path it prints is missing a component,  
specifically, the new/cur/tmp component.  For example:
/Volumes/Spool/user/maildir/12345.M123P123.example.com....
should be
/Volumes/Spool/user/maildir/cur/12345.M123P123.example.com....

This is using dovecot-1.1.10.

Now I just have to figure out why the file is corrupted in the first  
place.
