Thanks. I can see this in emacs 22.3, but it seems to be already fixed
in the current CVS trunk, so will be fixed in Emacs 23.1.

In emacs 22.3 any attempt to tab complete a local filename in a buffer 
which is visiting a remote file using tramp results in a "Not a tramp 
file name" error.

In other words if I just do C-x C-f to load a file, and starting a local 
filename without first killing the minibuffer contents, then I get that 
error if I hit tab to do completion.

The reason for this is the addition of a call to substitute-in-file-name 
at the top of tramp-file-name-handler. This was intended to expand 
environment variables but has the side effect of removing the tramp 
filename from the start of the buffer leaving just a local filename.

When that value is then passed to with-parsed-tramp-file-name it raises 
the error when it tries to dissect the name.

I guess the solution is to check the foreign flag before making the call 
to with-parsed-tramp-file-name and if it is not set to just pass the 
operation on?

Tom
