[Dovecot] Panic: file sieve-cmu.c: line 262 (part_save): assertion failed: (buf->used - 1 == part->body_size.physical_size)

[Maciej Polewczyński]

Hello

Dovecot v1.1.3
Sieve plugin v1.1.5
Debian Lenny
Virtual users in mysql db
dovecot -n at the end of email

I have problem with sieve body rules during delivery. When I test rule

if body :raw :contains [ ".exe" ]
{
        discard;
}

deliver die with panic:

Is there a bug or I have done something wrong.
