dovecot - Jun 2008 - assertion after upgrading to 1.1rc7 from 1.1rc3

Hi,
    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

Could you make a copy of dovecot.index and dovecot.index.cache files
before deleting them and send them to me?

I did one fix yesterday to this function:
http://hg.dovecot.org/dovecot-1.1/rev/c008dde3c973

Does it still crash when that is applied?

I did several fixes to sort indexes:

http://hg.dovecot.org/dovecot-1.1/rev/5824e6f1d279
http://hg.dovecot.org/dovecot-1.1/rev/63602977ca9b

Hi,
  this seems to have done it! I've applied the former patch as well as
these ones to all our servers and haven't seen that error for over an hour.

Thanks,
