Comment 1 for bug 711145

I verified that a whitespace real name can indeed be registered, and that it causes an oops on attempt to log in to Launchpad.

Steps to reproduce:
1. Go to https://staging.launchpad.net/
2. Click "Log in / Register"
3. Click "Create a new account"
4. Enter account details, using a single space as the "Full name". Click Continue.
5. Wait for confirmation email, and enter its confirmation code into the browser (or follow the link given in the message).
6. Click "Yes, sign me in" to proceed to Launchpad.

Actual result:
  Oops!
  Sorry, something just went wrong in Launchpad.

  We’ve recorded what happened, and we’ll fix it as soon as possible. Apologies for the inconvenience.

  (Error ID: OOPS-1887L1654)

Expected result:
Rejected registration without a meaningful full name, or successful login.

Additional notes:
- Changing the full name to a non-whitespace value (for example, the letter 'k') is sufficient to enable successful logins on Launchpad.
- The login.launchpad service's account edit tool does not allow changing the full name back to a space.
