Comment 7 for bug 350732

Here is how to extract the patch from the upstream svn repo (their svn web interface doesn't work):

  svn checkout http://svn.digium.com/svn/asterisk/branches/1.4 asterisk-1.4
  cd asterisk-1.4
  svn log -r 181340
  svn diff -r 181339:181340

(The revision number is from the upstream bug linked to above)
