Any creditor may, in case of a vacancy in the office of assignee or receiver, petition the court for the appointment of a new assignee, whenever he may have reason to believe that there are assets of the assigned estate that have not yet been collected, or that any duties appertaining to the office remain unperformed; and such appointment shall be made by the court with the same effect as in a case of the original appointment.
