error on using tools-drc

saw this error when using the tools-drc menu option:

 File "/usr/lib/rhythmbox/plugins/DRC/DRCConfig.py", line 35, in load
    cfgFile = open(self.cfgFileName,'r')
FileNotFoundError: [Errno 2] No such file or directory: '/home/dad/.cache/rhythmbox/DRC/DRC.xml'

During handling of the above exception, another exception occurred:

can confirm that the folder /home/dad/.cache/rhythmbox/DRC does not exist. Had a quick look at the code - may test that the folder exists - if not create it

if not os.path.exists(directory):
    os.makedirs(directory)

before opening the file.
