In the new Qt registration dialog, there is no way to simply log in, if you already have an account. Also, there is no way to register from a log-in dialog, if you don't have an account. This means that in order to get the right dialog, the program which needs access, needs to already know whether or not you have an account, which is not possible.

This is a regression from the GTK+ dialogs, which had an "I already have an account" link button in the registration dialog.
