tramp 2.1.6: hosts completion does not work for me.

[Pawel]

Hallo
After upgrading to 2.1.6 I found out that hosts tramp completion does not work.

I am using scp as default method. The same method I used in 2.1.5.

I got the trace from my correctly running tramp 2.1.5 and found that completion 
goes through tramp-completion-file-name-handler.

I put a breakpoint to that method in tramp 2.1.6 (edebug-defun), but debugger 
does not stop there. 
I also added message there, but no success.

my emacs is:
GNU Emacs 21.3.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars) of 
2005-02-04 on bugs.build.redhat.com

I did not compile tramp (neither 2.1.5 nor 2.1.6). Instead in both cases I just 
unpacked it to separate directory end set up config according to tramp manual :

(setq pp-tramp-dir "/dir/with/tramp")
(add-to-list 'load-path (concat pp-tramp-dir "/lisp"))
(require 'tramp)

I believe that it does not matter to the problem I experience (completion works 
fine for tramp 2.1.5 indeed).

Greetings
