Upgraded squeeze-lts server to wheezy -- client exim4 connections over tls give segfault

["Andrew McGlashan" <andrew.mcglashan@affinityvision.com.au>]

Hi,
     I've been running squeeze-lts VM on a squeeze-lts Xen
server. Updated the VM to wheezy and it most ly works okay, but but mail  
 
connections fail with a segfault
     #�  swaks -4
-s mail.affinityvision.com.au -tlsc -p 465 --ehlo    
affintiyvision.com.au -au andrewm -ap�  -t    
andrew.mcglashan@affinityvision.com.au -f    
andrew.mcglashan@affinityvision.com.au

     === Trying
mail.affinityvision.com.au:465...
     === Connected to
mail.affinityvision.com.au.
     Segmentation fault
     If I
connect to a different machine running�  (even from the
/faulty/
    VM), it works fine.
     Other server:
    
#� � �  swaks -4 -s
mail.otherdomain.com� � � � � � � � 
-tlsc -p 465
