Bulk Upgrade link not working at signup

The "bulk upgrades" link on the /pro-site/ page does not work when the page is displayed at sign-up. i.e. just after receiving the login details for a new blog.

Clicking it just causes the page to refresh.

It does work when clicked after the user has accessed dashboard
for the first time.

How can I fix this or remove the bulk upgrades option in the instance where it is not working?
