Hello Glenn,

I did your test case on various systems with revision 111607. On all systems "C-x v v" did not work!

All changes applied successfully.                                              
Now on revision 111607.

Start emacs with:

$ src/emacs -Q /tmp/foo

  /tmp/foo:
  total used in directory 12 available 27576720
  drwxrwxr-x.  3 maierha maierha 4096 Jan 20 17:41 .
  drwxrwxrwt. 26 root    root    4096 Jan 26 10:05 ..
  drwxrwxr-x.  3 maierha maierha 4096 Jan 20 17:41 CVS
  -rw-rw-r--.  1 maierha maierha    0 Jan 20 17:27 file
  -r--r--r--.  1 maierha maierha    0 Jan 20 17:27 file.~1.1.1.1.~

Now open "file" and do "C-x v v". Emacs hangs and I have to do a "C-g".

Debugger entered--Lisp error: (quit)
  get-file-buffer("/tmp/foo/file")
  vc-next-action(nil)
  call-interactively(vc-next-action nil nil)

Additionally in the "*Messages*" buffer I find sometimes but not always:

ad-handle-definition: `vc-print-log' got redefined

With emacs-24.1 all works fine.
