[Dovecot] dovecot 1.1.2 assertion

[Nuno Lopes]

Hi,
  I've upgraded to last version of dovecot and am now getting the 
following assertions:

Jul 25 00:00:34 bld3 dovecot: Panic: IMAP(example1 at example.com): file 
index-sort-string.c: line 542 (index_sort_add_ids_range): assertion 
failed: (left_idx == 0 && right_idx == rightmost_idx)

If this is not enough for you to solve it ...

Some problems were solved upgrading from 1.1.1 but these ones remained.
