I get this backtrace below in certain cases when doing C-x C-f and entering

  c:/ema TAB

in the minibuffer. I have no good idea of how to debug it.

It happens only after I have loaded a multi major mode file. However
it happens not after just loading mumamo.el.

If I enter

  c:/emacs/something TAB

it does not happen either, i.e. it happens only before the second "/".

Tramp is loaded after the first TAB above but that is loaded in both
the cases where I get an error and those where I do not get it. (I
have no idea why tramp is loaded though.)

I do not know if I can track this down to something more simple so I
ask for suggestions and qualified guesses instead. Anyone has some?

This is with a checkout from 2010-05-22, my patched version.
