Upgrade to 1.5.1.0 Shows a 404 Error on the Frontend

I just upgraded a store from 1.4.2 to 1.5.1.0 and when I loaded the frontend I got a 404 error. This is a multi-store magento setup. The fix is to login to the admin, go to System > Manage Stores, find the default store (which is probably disabled) and simply enable it. Voila! The frontend works now. This must be a bug in 1.5.1.0.

Hope it helps someone!
