local variable 'custom_module' referenced before assignment

when trying to pair my tradfri dimmer i get the following error message:

Jul 05 14:33:22 home hass[68]:   File "/usr/lib/python3.5/asyncio/tasks.py", line 239, in _step

when looking at the code of custom_components/zha_new.py around line 382 i believe the error is correct.

configuration:

zha_new:
  usb_path: /dev/ttyUSB0
#  radio_type: ezsp
  database_path: /home/homeassistant/.homeassistant/zigbee.db
  device_config:
    "00:0b:57:ff:fe:3a:48:cb-1":

      type: switch
      config_report:

btw, tradfri dimmer should be detected automatic. no need for a device entry.
