Possible problem XPath

In the XPATH module gdome_xpath_xpeval_createResult, note that it calls
gdome_xpath_xpresult_mkref passing NULLs. This is turn calls
gdome_xml_n_ref (gnode, &exc) that fails if it receives NULL.
Unless I am not seeing something, I think there is a problem here and
would like to report that to the team...
Thanks,Alex
