                    disposed while preparing
           Product: Telepathy
           Version: unspecified
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: tp-glib

If the account manager is destroyed while   tp_account_prepare_async (account,
fs, _tp_account_manager_account_ready_cb, manager); is running, we hit this
crash in the callback.
