restkit obscures connection error messages

When using restkit through couchdbkit, connecting to a server that isn't actually running couchdb produces a very confusing error message. For instance, this code

import couchdbkit
s = couchdbkit.Server('http://192.168.0.10:5984')
d = s['bar']
print list(d.all_docs())

gives this exception

Traceback (most recent call last):
  File "foo.py", line 5, in <module>
    print list(d.all_docs())

    raise RequestError("socker.error: %s" % str(e))
restkit.errors.RequestError: socker.error: getaddrinfo returns an empty list

even though getaddrinfo returns correctly and the real problem is that the connection is refused.
