Package: libxml2
Version: 2.8.0+dfsg1-7+wheezy2
Severity: important

Dear Maintainer,

After security upgrade of the package from version
libxml2_2.8.0+dfsg1-7+wheezy1_amd64.deb to
libxml2_2.8.0+dfsg1-7+wheezy2_amd64.deb, sylkserver application (http://ag-
projects.com/debian/pool/main/s/sylkserver/sylkserver_2.7.2wheezy_all.deb with
http://ag-projects.com/debian/pool/main/p/python-sipsimple/python-
sipsimple_1.4.2wheezy_i386.deb ) does not anymore start.  The application
starts and works fine if I downgrade libxml2 back to
libxml2_2.8.0+dfsg1-7+wheezy1_amd64.deb.

At start, the application produces the following error messages:

I would not expect a security upgrade of a library package to change its
behavior so that applications using the library suddenly stop working.
