error message while help command

[block]

When I run "help config max_active_limit" (or any other config parameter) in deluge-console the following error message pops up:

global name 'usage' is not defined
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/deluge/ui/console/main.py", line 344, in do_command
    ret = self._commands[cmd].handle(*args, **options.__dict__)
  File "/usr/lib/python2.7/dist-packages/deluge/ui/console/commands/help.py", line 53, in handle
    self.console.write(usage)
NameError: global name 'usage' is not defined

Actually there is no help for specific config attributes so it's trying to show Usage: help [command] but there is a typo in code.
