That is documented to be only for temporary debug purposes: http://docs.djangoproject.com/en/dev/ref/templates/api/#invalid-template-variables. Attempting to use the admin with TEMPLATE_STRING_IF_INVALID set to something other than the empty string is not a good idea -- admin is one of the specific apps noted as relying on the default value of an empty string for invalid variable references in templates.
