If you do a CD or a DVD copy using brasero, nautilus-cd-burner or any burning tool, it will first create an image of the media, then ask for the blank media, and finally write the image on it.

The problem with Nautilus is that, whenever you insert the blank media, it detects it and does whatever the user has configured it to do with it (launch a CD burning appliation for example). But in this case, Nautilus should just ignore the insertion of the media because the media is inserted on request of another application.

So, what I propose is that CD burning applications should have a way to tell Nautilus to ignore media insertion while a copy is in operation.

And I guess that a generic way for applications to tell Nautilus to ignore media insertion could even be useful for other use cases where an application needs the user to insert a media to perform an operation on it.
