Summary:                    On receiving Fax with ReceiveFax Asterisk core dumps
Description: 
I have Asterisk 1.6.2.6 running with Digium res_fax and res_fax_digium

On restarting Asterisk i see the following message in Asterisk Message
Log:

[Mar 25 15:01:43] WARNING[7822] loader.c: Error loading module
'res_fax_digium.so': /usr/lib/asterisk/modules/res_fax_digium.so: undefined

In Asterisk i see that the module is loaded, but when ever i try to send
or receive a fax asterisk coredumps ...

I tried to enable debug on "fax" but i get no output at all...

I got this bug on Ubuntu 10.04 Lucid Lynx and found this ticket.  The fix
suggested by lmadsen worked for me, but I needed an extra noload line like
this:

  # /etc/asterisk/modules.conf
  [modules]
  autoload=yes
  noload => app_fax.so
  preload => res_fax.so

This was being logged and causing asterisk to return and exit on 1.
