Name registration fails with no helpful message

[Josh Arenson]

Terminal output is pretty explanatory

josh@blackbox:~/mysnap$ snapcraft login
Enter your Ubuntu One SSO credentials.
Email: <email address hidden>
Password:
Second-factor auth: XXXXXX

Login successful.
josh@blackbox:~/mysnap$ snapcraft register <actual-unique-snap-name>
Registering <actual-unique-snap-name>.
Registration failed.

??? But why?

Note that Josh got a permission error, even after login out and back in again to regenerate a macaroon:

Update:
I was able to register my snap name through the web interface. The webUI asked me to create a developer namespace, something the cli tool had not asked me to do. I assume that had something to do with it working. Ping me on IRC @josharenson (GMT -8) for any more info.

Thanks Josh. We have a handful of bugs to report better error messages when something is missing in the store.
