[Telepathy] papyon 0.5.2 to 0.5.4 causes error: AttributeError: 'Profile' object has no attribute 'infos'

[Frederik Himpe]

Since papyon in Debian experimental was updated from 0.5.2 to 0.5.4,
empathy 2.30 from Squeeze does not show my MSN contacts anymore. This
backtrace can be found in empathy's debug logs:

tp_contact_list_got_added_members_cb: Error:
