The function is OK (the _wanted form is the preferred one) but
entering the completion system directly at menu-select is likely to do
odd things---most of the controls assume the completion system itself is
in charge of setting up menus etc.

Try using the function in the following manner (this replaces your "zle
-C" line):

zle -C x complete-word _generic
zstyle ':completion:x:*' completer _x
zstyle ':completion:x:*' menu select

Now you're entering the completion system the normal way, but with the
styles set to use menu selection.  This should work better.  Obviously,
if you use a more descriptive name, the "x"s in the style context need
to change, too.

See the description of the _generic completer in the zshcompsys manual.
