  A problem with libxml :-)

  Right, and Fred Drake triggered that as a bug
    http://bugs.gnome.org/db/35/3504.html

So basically I changed xmlSetProp() and xmlNewProp() to do the
call to xmlEncodeEntitiesReentrant() so that the functions
New, Set and Get are at the same level. This makes far more sense
and I hope won't break too many things, this should be commited within
an hour in CVS.
