Hello,
I have a hackrf board which I am able to use using gqrx (using Ubuntu 14.04
LTS, gnuradio v3.7.10.1-182-g59136936). This, I guess, confirms the
permissions issue for accessing hackrf under my username.
However, when I try to execute a flow graph I created using
gnuradio-companion, it fails for the following reason:
Generating: '/mymachine/sdr/gnuradioProjects/flowGraphsFromGRC/top_block.py'

This is being done to prevent the application from crashing
due to gnuradio bug #528.
Traceback (most recent call last):

Any help is appreciated.
Thanks,
Sonny.
