feisty: gajim does not start up correctly

Binary package hint: gajim

gajim does not start up correctly and produces quite some output when started from console, the last lines being:

  File "gajim.py", line 432, in handle_event_status
    self.roster.on_status_changed(account, status)
  File "/usr/share/gajim/src/roster_window.py", line 3038, in on_status_changed
    self.chg_contact_status(contact, 'offline', '', account)
  File "/usr/share/gajim/src/roster_window.py", line 1203, in chg_contact_status
    self.add_contact_to_roster(contact.jid, account)
  File "/usr/share/gajim/src/roster_window.py", line 315, in add_contact_to_roster
    shown_family)
  File "/usr/share/gajim/src/common/contacts.py", line 419, in get_metacontacts_big_brother
    score = self._get_data_score(data)
  File "/usr/share/gajim/src/common/contacts.py", line 399, in _get_data_score
    score = (max_order - order)*10000
TypeError: unsupported operand type(s) for -: 'unicode' and 'unicode'

It seems that the XML handling converts the attribute "order='0'" to return a unicode string instead of a simple number where arithmetic operations could be applied on. According to RFC 3921 the order attribute contains an unsigned int so that cast should be safe.

TEST CASE: Run Gajim on the console and the exception given above is printed in it. Depending on the roster it could lead to it being unusable.
