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

[Raffael Schmid]

Hi everybody

We are running in the same issue as Maciej Polewczynski does in
http://www.dovecot.org/list/dovecot/2008-September/033645.html

Is there already a solution? I dont think so? In the TODO-File for 1.2.2
this issue is still reported:
####
[...]
 - sieve-cmu.c crash: i_assert(buf->used - 1 ==
part->body_size.physical_size);
[...]
####

I am not able to reproduce the problem but I think it has something to
do with the charset of a mail? Because the 2 bits which are used with
UTF-8 for special characters?

Dovecot is running in a 64bit vServer on a 64bit host. Both are debian
lenny with all patches. The dovecot-packages is backported.

Just write me if you need more informations.

Raffael
