No override needed in notifications.py The only downside is that the ?s=0 parameter will still be appended but is not handled in list(). The right solution would be to update list() so that it does say "Message Sent" or such, to give the user an indication that their message was sent succesfully. Patch by: Sverre Rabbelier

 This module houses the OGR & SRS Exception objects, and the
 check_err() routine which checks the status code returned by
 OGR methods.

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that
    django's templates proceed to use the next lookup type gracefully when
    an Exception is raised.  Fixes ticket #4740.
