Sigh...  

The interaction between ido and tramp is very hard to get right.

What ido tries to do is to ask tramp (indirectly via a call to
file-name-all-completions) to provide a list of possible completions
for each step of entering the "tramp prefix".

The problem is that tramp needs to get the partial string in certain
formats for it to do the right thing, and I belive I got it working
quite some time (years) ago, but some later changes to tramp must have
broken it.

I'll see what I can do about it...

In the meantime, you can set ido-enable-tramp-completion to nil.

This happens to me too.  Thanks for noticing it.
