v2.0 crashes if no config file

PLSDR v2.0, Arch linux, rtl_sdr dongle

Troubleshooting another issue, removed ~/.PLSDR/config.ini file resulting in:

tried removing entire ~/.PLSDR directory, this would be the state in a fresh install I guess, results in same.

Tried moving the rtl_sdr to top of list in device_dict of PLSDR.py, same result

Although most likely a GNURadio library bug, try reinstalling gr-osmosdr. Try this:

   $ sudo apt install --reinstall gr-osmosdr

I suspect that Arch doesn't use "apt", sorry, the above may need translation.

But after some research, I see this is a known problem in a GNURadio library with no clear resolution:

I forgot to ask -- do you have an Airspy device? If so, do you see this crash if the device is not connected?

Again, I hope this helps.
