It is an warning which does not break the site, only shows up with debugger on.

empty check to fix the issue.

Could you provide the steps to reproduce the issue? Why would get_bloginfo( 'url' ) return a URL without a host name?

[meekyhwang]

It happened when I tried to install the site for the first time when it redirected to /wp-admin/install.php. (the warning appeared on the screen where it asks you to set up the language before setting up the site admin account.) get_bloginfo( 'url' ) is not set at this point.
