    I'm getting this assertion after making an upgrade from 1.1rc3 to
1.1rc7. Deleting the index files solves the problem. This seems to
happen only to some accounts but I haven't managed to find which ones.
I'm using dovecot's deliver to deliver the messages.

Panic: IMAP(user at example.com): file index-sort-string.c: line 575
(index_sort_add_ids_range): assertion failed: (strcmp(left_str, str) < 0)

Here goes the output of dovecot -n
