    dispatcher_request_failed: check if conn_data is not NULL
    
    Trace attached on lp #392678 seems to indicate that the
    priv->connections hash table doesn't have a ConnectionData associated
    with the connection. A possible explanation could be that this
    connection has been invalidated before the RequestChannel call is
    terminated.
    
    Check if ConnectionData so Empathy won't crash in such case.
