Bug#570095: java.lang.NullPointerException: at org.apache.fop.layoutmgr.inline.InlineStackingLayoutManager.applyChanges(InlineStackingLayoutManager.java:350)

[Mathieu Malaterre]

I can reproduce it also in my sid chroot system:


# xmlto pdf test.xml
Making portrait pages on a4 paper (210mmx297mm)
PassiveTeX is needed for this format, but it is not installed. Please install
the passivetex package.
gotlib# xmlto --with-fop pdf test.xml
