[xml/sgml-pkgs] Bug#648859: libxml2: leaked namespaces when reusing a xmlReader/xmlParser

[Pierre Habouzit]

Package: libxml2
Version: 2.7.8.dfsg-5
Severity: normal

If you reuse an xmlTextReader and you interupted the previous parse done
with it, its namespace stack isn't reset, and the subsequent parse get
lots of namespacing errors reported (what a surprise).
