[Pymilter] pymilter segfaults

[Michal Mach]

Hi

I am using pymilter with postfix and implemented a milter for disclaimer
appending.
The problem is that occasionally it simply crashes because of a segfault.
The error in dmesg:

mimemilter.py[23082]: segfault at 0000000000000130 rip 00002acb089e8900 
rsp 00000000410010f0 error 4

Similar problem was discussed in this mailing list here:

http://www.bmsi.com/pipermail/pymilter/2007-January/000143.html

But it seams this discussion had no result what could be the problem.
OS and packages are as follows:

Debian lenny
libmilter1.0.1      8.14.3-5
python-milter       0.8.9-3
python2.5           2.5.2-11

Using only standard python2.5 packages (email, logging, cStringIO, 
codecs, os, sys)
Can you give me some suggestions what could be the problem?
If you need more info please drop me an mail.
