I found a bug that I haven't seen reported. It seems that if you try to
include a SVG file with an empty text element you get a null pointer
exception. This only occurs if you use userconfig.xml file and set
<entry><key>strokeSVGText</key><value>false</value></entry>
If you have an SVG with an empty text element (eg: <text />) you get a null
pointer exception. If you put in some CDATA like<text>hi</text> it works.
It also works if you remove the user config file so you don't render the
text directly into the PDF.
Below is the exception I get.
