It is a moderated list. There might be a delay of some few days, when
Adrian, our very responsive moderator, is offline.

Tramp has some optimization code which applies a direct copy when Tramp
"believes" it is on the local host. Your tunnel via port 10000 makes
Tramp believe it. Hmm, bad.

I'll check whether I can fix it. For the time being, you might not
establish a tunnel but use Tramp's multi-hop feature. See the Tramp
manual, section "Multi-hops". Note that you must use the "ssh" method
instead of "scp"; the latter one is not suited for multi-hops.

I'll come back when I have fixed it.
