Segfault with amavis 2.6.6

[Urban Loesch via amavis-users]

Hi,

yesterday I made an OS upgrade of one of our multiple mailfilters from Debian "squeeze" and "amavis 2.6.4" to Debian "wheezy" and "amavis 2.6.6".

Since that I got somethimes the following error in my logs:

Have you any idea how can i solve this?
Upgrading to a newer version of amavis is currently not possible due to lack of time.

Many thanks
