[xml/sgml-pkgs] Bug#327659: libxml2: 2.6.21-1 breaks xsltproc

[Roger Leigh]

Package: libxml2
Version: 2.6.21-1
Severity: critical
Justification: breaks unrelated software

Hi,

The new libxml (2.6.21-1) breaks xsltproc, which makes a rather large
number of packages fail to build from source.  Reverting to 2.6.20-1
fixes this, showing that the new version is the root of the problem.

An example failure follows (trimmed), in this case gtk-doc-tools using
xsltproc as part of the schroot build.  It has also broken other
packages such as happy, and others.
