    Retrieval of the first transition of the current state can crash if there is no changeset or the changeset value for the field does not exist
    In some cases we might have no changeset value for a field (see for example this other issue: request #13376). If a workflow is enabled on this field, the retrieval of the workflow information might lead to a PHP fatal error.

    Even this situation is not supposed to happen, the code should take into account all possible values exposed by the internal API.
