Description

I encounter a java.lang.NullPointerException with fop 1:1.0.dfsg2-6
when processing a valid docbook 4.5 file. If an anchor is placed inside an
emphasis element, the produced .fo file will make fop crash.

I attach some sample files showing the problem.

The steps to reproduce the bug are the following:

vincent@hal:~$ /usr/bin/xmllint --postvalid --noout --nonet fop.segv.xml
vincent@hal:~$ echo $?
0
vincent@hal:~$ /usr/bin/xsltproc --stringparam use.extensions 1 --stringparam fop1.extensions 1 --stringparam tablecolumns.extension 0 --stringparam callouts.extension 0 -o /home/vincent/fop.segv.fo /usr/share/xml/docbook/stylesheet/docbook-xsl/fo/docbook.xsl /home/vincent/fop.segv.xml
