11970	JSON Deserialiser throws ValueError on malformed input	Malcolm Box	nobody	"/core/serializers/json.py Deserializer uses simplejson to parse the input string.  If this input is malformed, then simplejson throws a ValueError exception.

However, the serializer interface appears (see XML & base.py) that it should raise a  base.DeserializationError when deserialization fails, not a ValueError.  Users of the deserializer (e.g. django-restapi) then fail to handle the ValueError, resulting in Internal Server (500) errors.

The fix is to catch ValueError in json.py (around line 40) and re-raise as a DeserializationError.

Simple patch attached.
