Describe the bug

I'm using yowsup with transwhat and this looks like a yowsup issue (please correct me if I'm wrong):

/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"

Found protobuf issue #3002 that's most probably related.

Bumping this as I still got that error with:

yowsup-cli v3.2.1
using:
  yowsup v3.3.0
  consonance v0.1.5-r1
  dissononce v0.34.3-r3
  python-axolotl v0.2.3-r3
  cryptography v39.0.1
  protobuf v21.9

Any hint appreciated.
