It is by practical consideration found out that the structure does not work
Dovecot+Sieve+Kaspersky Antispam.
Finally mail to the user is delivered, is lost nothing but only through a
considerable quantity of errors.
At Spam-filter switch-off dovecot-lda does not fall.

The given error repeats again when KAS starts to check spam. The best
method to receive it to use a small e-mail the generator:
PHP:
<?
for ($i=1; $i<=25; $i++)
{
$from = "john at example.com";
$to = "john at example.com";
$subject = "Test message";
$message = "This is the TEST";
mail  ( $from, $to  , $subject  , $message );
}
?>

Could you first try whether the following change fixes the problem:

http://hg.dovecot.org/dovecot-2.0/rev/e2f9baa436f2

If that doesn't help, a gdb backtrace would be very helpful:

http://www.dovecot.org/bugreport.html

Regards,

Stephan.

Problem solved:

http://hg.dovecot.org/dovecot-2.0/diff/e2f9baa436f2/src/lib-storage/index/maildir/maildir-save.c

Thanx for Stephan Bosch.

PS.: The main thing that in new version Dovecot this correction has been
installed.
