protobuf: "A file with this name is already in the pool."

Transwhat doesn't launch. It looks like a yowsup issue but I'm not 100% sure and maybe transwhat can work around it:

$ /usr/bin/transwhat --debug --host 127.0.0.1 --port 33760 --service.backend_id=1 "-j" "whatsapp.example.com" "/etc/spectrum2/transports/transwhat-whatsapp.cfg"
