The security bugfix for SIP/IAX realtime added in 1.2.26 tries to 
dereference lots of null pointers - to the point that stock 1.2.26 is 
unusable for me.

There are fixes for this in svn branches/1.2, but not in an official 

I've put the relevant diffs from SVN up as a patch, in case anyone wants 
them who isn't comfortable with diffing around svn revisions:
