Comment 0 for bug 376759

[How to reproduce]

1) Install ubuntu-one client
2) click Application->Internet->Ubuntu One, you will see sign-up page{*1} in your browser.
3) close browser tab of sign-up page without signed-up.
4) re-click Application->Internet->Ubuntu One

{*1} sign-up (and/or) machine registration page.
     https://ubuntuone.com/oauth/authorize/?oauth-----

[Actual results]
You can retry sign-up process.

Background behavior is:
  Process "/usr/bin/python /usr/bin/ubuntuone-client-applet --signup" was killed,
  and new process can exec normaly.

[Expection]
You cannot retry. Login page was not opened in your browser.

Background behavior is:
  Process "/usr/bin/python /usr/bin/ubuntuone-client-applet --signup"
  was still waiting for signed-up.
  And, whit this is root problem, new ubuntuone-client-applet killed by
  "Ubuntu One client applet already running, quitting".

This is bad behavior, particularly for beginners.

[Workaround]
a) kill your process "/usr/bin/python /usr/bin/ubuntuone-client-applet --signup"
b) logout your session.
