Comment 5 for bug 450633

The main issue here is that the client.py, from storageprotocol, confuses both errors, so ActionQueue can not distinguish them.

I'm thinking a solution along this way: client.py will separate the errors, and AQ will trigger unknown error in case of server internal error, and auth error in case of auth error only. The applet could still behave like now, but the token dropping will not be triggered by timeouts in the server.
