"tramp-completion-file-name-handler: Recursive load" with the trunk code

[an0]

I met an error as follows starting emacs compiled from today's trunk code:
tramp-completion-file-name-handler: Recursive load:
"/home/xxx/share/emacs/23.0.60/lisp/net/tramp.elc",
"/home/xxx/share/emacs/23.0.60/lisp/net/tramp.elc",
"/home/xxx/share/emacs/23.0.60/lisp/net/tramp.elc",
"/home/xxx/share/emacs/23.0.60/lisp/net/tramp.elc",
"/home/xxx/share/emacs/23.0.60/lisp/net/tramp.elc",
"/home/xxx/share/emacs/23.0.60/lisp/ibuffer.elc"

And any subsequent nontrivial operations cause the same error to recur
again and again, which renders my emacs completely useless.

After some tracing, I found it was probably caused by ido, because the
problem disappeared after I commented out following code in my .emacs:
  (require 'ido)
  (ido-mode 1)
