The reporting of lines in gir is, at best, very approximate (look at the
previous or next element of where it reports). The problem here is in
XmlNode :
1226    <record name="XmlNode"
...
1247      <field name="next" writable="1">
1248        <type name="XmlNode" c:type="RestXmlNode*"/>
1249      </field>

And here is the recursive type :-)
You could try to mark this field as allow-none (I'm not if it's possible
to do it with g-ir-scanner, you may need to modify the gir manually).

HTH,
