It still happens for users 1-2 times a day. I think it's due to that 
"Error: Maildir filename has wrong S value, renamed the file from" is 
only ran for first occurance.

So for some users that only have few broken sizes in maildir filenames 
they won't even notice it as after few crashes the mailbox is ok.

When only that first filename is renamed and index fixed for that one 
mail and user uses search it then crashes as some of the other mails 
have smaller on disk size than S=/index has.

The crashes also go away when index files are removed and that 
fix-maildir.pl ran from your site for that particular user.

Thanks,
Toni
