Thanks Marcus,
I did not realize about indentation in python.
I have corrected this by using tabs only as used by similar structures
in the same file.
On running grc I get:

[baz@jackodesktop gnuradio]$ gnuradio-companion
Traceback (most recent call last):

KeyError: 'options'

The patch applying your change is attached.
