FYI this is a few bugs and bug fixes ganging up to crash.

The first bug was (it is fixed since *2016* - https://github.com/gnuradio/gnuradio/commit/11973c64437683cc99c48eae9eb4db8234f1ac42#diff-6afde48a2246887a22e0cbe0a675e1c8) in GNUradio #528.

A work around was added to rtl-sdr (which is the "Trying to fill up.." message) which is at https://github.com/osmocom/gr-osmosdr/blob/5ecfa255d299b9b4842ccd09a02892a853fcd5a7/lib/source_impl.cc#L413

The second bug is p25_demodulator.py crashing because it doesn't detect self.decim is zero.

It looks like gr-osmosdr now has the work around removed (since July 2017) - https://github.com/osmocom/gr-osmosdr/commit/ea6b356cfda8a90fa6d727fcc13aae60547962a2

tl;dr:
- It didn't find your hardware, check your VM pass through
- Update gr-osmosdr to get less confusing errors :)
