Re: [U2] XMAPOpen core dump

I find the most common reason for a core dump when dealing with xml is the
lang settings and encoding of the files.   make sure they match - I note
the xml is utf-8 - firstly check it is indeed utf-8 and there are no upper
ascii (above 127) in there. Also make sure you have a lang setting that
matches utf-8  lang=c wont work.
