xsltproc segfaults in xsltApplyTemplates

Hi,

trying to transform the following docbook snippet causes xsltproc to 
segfault. The culprit seems to be the <affiliation> tag within the 
<authorgroup>. I'm using the XSL stylesheets v1.61.2. I already filed a 
bug report here: http://bugzilla.gnome.org/show_bug.cgi?id=114846
