ssh not working with ido

[Colin Baxter]

I am unable to ssh into another host using tramp if I use "ido". My procedure of
C-x C-f /ssh:address@hidden:/home/username/path/to/file works with emacs-25.1. 
With emacs-26.0.50.1, however, I get the error:

tramp-file-name-handler: Host name must not match method "ssh"

as soon as I enter a colon after /ssh

If I commit out the calls to ido in my ~/.emacs, I can successfully ssh
into a remote host. I would appreciate any suggestions of where to begin
for a work round.

I have tried to revert the commit 6647e ok Nov 14, but it wont let me. I
have also read the  "Connection-local variables can be used to specify
local variables" section in /etc/NEWS, but I don't usefully understand
what I'm reading - sorry.

I am using Debian 3.2.82-1 i686 GNU/Linux.

Colin.
