Error on page validation: org.apache.xmlbeans.XmlException Unexpected end of file after null

Dear w3-Team,

I got an error on validating the page http://www.magnitudo.org and the 
site told me to send feeback to you:
"Es ist ein kritischer Fehler aufgetreten. Unten steht ein 
Fehlerprotokoll von Unicorn. Kopiere es bitte und sende uns diesen 
Fehlerbericht, um uns bei der Lösung des Problems zu helfen."

After trying a second validation the error didn't occur any more.
Date: 2013-10-28 about 12:15  in UTC+01:00 (Germany)
The stacktrace:

class org.apache.xmlbeans.XmlException
error: Unexpected end of file after null
org.apache.xmlbeans.impl.store.Locale$SaxLoader.load(Locale.java:3486)

Hope it could help a bit...
