[Sugar-devel] How to start the Browse activity from my own activity?

How to start the Browse activity from my own activity?

My Kandid activity can dump internal states as a HTML files. For
example this information is written to
~/.sugar/default/net.sourceforge.kandid/tmp/_znuaxz_169/index.html

Now I am searching for a possibility to launch the Brows activity
displaying this HTML file.
First I tried using  the webbrowser.open() method from Python. But no
effect when running under SoaS release 2 (Bluberry) Sugar 0.86.3

def on_explain_activate(self, *args):
    ka_debug.info('on_explain_activate [%s]' % args[0].get_name())
    protozoon = self.model.protozoans[name_to_index(args[0].get_name())]
    folder = os.path.join(self._activity_root, 'tmp')
    file_path = 'file://' + self.explain('html', protozoon, 'index', folder)
    #Start up a new instance of the Web activity.
    result = webbrowser.open(file_path)
    ka_debug.info('webbrowser.open: [%s] %s' % (file_path, str(result)))


My second try and error version is using the
activityfactory.create_with_uri() method.
But it will produce an exception when running with SoaS Bluberry.

def on_explain_activate(self, *args):
    ka_debug.info('on_explain_activate [%s]' % args[0].get_name())
    protozoon = self.model.protozoans[name_to_index(args[0].get_name())]
    folder = os.path.join(self._activity_root, 'tmp')
    file_path = 'file://' + self.explain('html', protozoon, 'index', folder)
    #Start up a new instance of the Web activity.
     ka_debug.info('webbrowser.open: [%s]' % (file_path))
     activityfactory.create_with_uri('org.laptop.WebActivity', file_path)
