We use xml::libxml version 2.0016 only and the thread you had referred mentions about higher versions like 2.5 and 2.6 etc. Are you sure, this could be the issue. If so , please advise if switching from 2.0016 to 2.5.11 is advisable ?
update: Sorry i got confused between xml::libxml version and libxml2 version. The XML::Libxml (2.0016) is linked to libxml2 version 2.7.8 which is later than 2.5.11 only.
