 ok - try a git pull from http://github.org/lkcl/webkit/16401.master -
i've disabled the g_return_val_if_fail() macros so that NULL can be
passed in to all arguments - if you get a segfault somewhere in WebKit
"core" code, you know you shouldn't have passed in one of the
arguments as NULL :)

 try this:
  res = gdom_document_evaluate(doc, exp, GDOM_NODE(body), resolver, 0, NULL);
 or even this:
  res = gdom_document_evaluate(doc, exp, NULL, resolver, 0, NULL);
