And how did you create it when it's illegal?
Usually this happens when namespace names change, so that formerly it didn't start with a namespace prefix but now it does. Since both namespace names in this case are canonical and will always exist, I'm not sure how it came to be.
Pages named "Talk:NS:Foo", where "NS" is a valid namespace name, used to be allowed until fairly recently, but they never worked particularly consistently. See https://bugzilla.wikimedia.org/show_bug.cgi?id=5280 for details.
