Yeah likewise - I have debugging but not enough (so will dig deeper).
My problem indicates the mime acl is at fault.
Disabling the mime acl fixes the problem.
Even the following config still causes a segfault:
acl_smtp_mime = acl_check_mime
acl_check_mime:
accept
#0 0x000000000048b877 in mime_acl_check ()
