I have set up a few default transfer methods (external) for a few
boxes as an alist.
But I don't think that should affect this.

I don't have access to my setup right now (its at work) - but as far
as I can remember - the body (that tries to fetch the correct property
remotely) doesn't get evaluated.
I shall take a look tomorrow and send you a trace.
On a side note - I would like to get involved in tramp development -
are there any small tasks / bugfixes that you can think of - that
would help me get a good grip on the source code ?
