Yes, I see a track list. (Just as I do with k3b):

Well, that looks like what appears in the address bar; so konqueror/dolphin is
definitely being told the correct drive (which I think we knew anyway, since
the other actions in the list (k3b and VLC) both access the drive correctly).
FWIW, before I installed wheezy on this system I was running Kubuntu, and that
didn't have this problem.
