That "Command attempted to use minibuffer while in minibuffer" is
because icomplete triggered a Tramp connection which tried to use
the minibuffer to get a password.
So if you add (setq enable-recursive-minibuffers t) to the above recipe
you can reproduce the problem.

I don't think Tramp should attempt a connection in that case since
(according to M-x trace-function RET icomplete-completions) the password
prompt happens during the call to icomplete-completions which binds
non-essential to t.
