The notification is truly about the icon itself being ready, not the  
URL.  And yes, it is dependent on the IconDatabase.  Currently, if the  
IconDatabase is not enabled, we never download site icons.

If all you care about is the URL, you can grab it and start  
downloading the icon anytime after the <head> element is finished
