setting GRPC_TRACE to any value causing hanging

[jefhil]

using " ./run_assistant_audio --verbose --credentials=credentials.json" works perfectly after export GRPC_TRACE=all (or anything at all) and repeating command it hangs. I'm on a Raspberry Pi with code cloned on 7/24/18

I've seen the same problem on another dev board. I couldn't find out the root cause until now.

Does that work if you run ./run_assistant_text?

./run_assistant_text hangs too

./run_assistant_text hangs for me too, no output, nothing:
