configuration wizzard: after choosing the corporate demo, I get a 404 error

After choosing the corporate demo for being imported, I get a 404 error when server tries to access the http://localhost:8080/cms page.

Here the problem is that the configuration menu tries to access this url (which it can actually do) but the import job is not quite done yet. I am able however to access this same page after going through the administration menu (i.e waiting for some time).
Attached to this JIRA is the log of the console.
