nepomuk_testdata cannot export claudia_sterns data into trig file

[enricominack]

I freshly started NEPOMUK and crawled the documents folder of claudia_stern. Then I started nepomuk_testdata (http://dev.nepomuk.semanticdesktop.org/repos/trunk/java/nepomuk_testdata/) to export the crawled data into a trig file, but it failed for the context

  file:/C:/home/claudia_stern/documents/SAP/q4_2003_final.ppt

with the exception

[Fatal Error] :73:25: An invalid XML character (Unicode: 0xb) was found in the element content of the document.

tried to fix it using XmlSafetyUtils?.wrapXmlSafeRDFContainer(container) but this fails miserably because of fucking classloader problems. tried a lot, failed miserably after 4 hours, can't fix it, sorry.

my state is attached as patch.

fixed in changeset:8926 by filtering out this unicode in ApertureDataWrapper. Still, the bad unicode can be added by anyone malicious.
