Comment 3 for bug 647367

Thanks for the very fast reaction.

another error this time:

Traceback (most recent call last):
  File "/usr/bin/mythbuntu-control-centre", line 264, in summaryApply
    plugin.user_scripted_changes(self.reconfigure_user[item])
  File "/usr/share/mythbuntu/plugins/python/mysql_configuration.py", line 165, in user_scripted_changes
    self.mysql.read_xml()
TypeError: read_xml() takes exactly 2 arguments (1 given)

and the errors about Jamu and backend are still there.
