Segfaults in indexer when after Maildir filename S value is updated
Every now and then the S value in the Maildir filname is wrong, and is
automaticcaly fixed by Dovecot while updating the index. It seems the
indexer retains a handle pointing to the old filename and crashes
immediately afterwards. The index is updated the next time the indexer
is run, is this is only an annoyance and somethign that fills up the
log.
