It seems there's a caller missing in GTK.

I think it's worth adding Attachment::isValid() or isNull() or bool operator

Now that I see this again, I find a bit weird that the returned fd that it's still owned by the attachment can be released. Could we remove the non const getter and make attachment.release().release() instead? or maybe keep the releaseFileDescriptor() method in attachment that returns m_fd.release() instead?

Less getters, more releasing.
