loading symlinked file raises vc error

[Dr. Thomas Baumann]

emacs-cvs of today (2004-10-15):

when loading a symlinked file the following error msg is raised 

vc-registered: Wrong type argument: stringp, nil

and the buffer does not show up, although the file is loaded and
accessible by switching the buffers

Example:

ln -s .emacs myemacs
C-xC-f .myemacs
--> vc-registered: Wrong type argument: stringp, nil

hardlinked files work.
