Oops! Just noticed that the name *does* have some relevance. With "simple" profile names, solid colors work correctly but gradients do not. With "fancy" names (in my case, Coated-FOGRA39--ISO-12647-2:2004-), the problem occurs both with gradients and solid colors.
Still, if you manage to select a profile and save the file, the profile information for that color does get saved.
