Pylint and Tornado - fails on @tornado.web.authenticated

Pylint crashes when it encounters @tornado.web.authenticated

class Handler1(tornado.web.RequestHandler):
    def get(self):
        return 'hello'

class Handler2(tornado.web.RequestHandler):
    @tornado.web.authenticated
    def get(self):
        return 'hello'

Pylint runs on a file containing Handler1. Pylint crashes on a file containing Handler2 reporting: decorator.expr.name == node.name): AttributeError: 'Getattr' object has no attribute 'name'

Traceback (most recent call last):

Is there a specific Pylint check that I can disable to stop this crash occurring?

This bug has been fixed in pylint repository and will soon be released (0.26 should be out next week). So either use a checkout (hg clone http://hg.logilab.org/pylint) or wait until next week

Looked through the code here. Disabling these has stopped the error occurring: [add these to config]

disable=E0100,E0101,E0102,E0106

pylint file -d E0100,E0101,E0102,E0106
