You could ensure that `My-shell-virtualenv-root' is string by using:
(unless (and My-shell-virtualenv-root
(stringp My-shell-virtualenv-root)
(string= "" My-shell-virtualenv-root))
and I guess you may do this too:
(unless (and (boundp 'My-shell-virtualenv-root) ;; that it is bound
My-shell-virtualenv-root ;; that it is not NIL
(stringp My-shell-virtualenv-root) ;; that it is string
(string= "" My-shell-virtualenv-root)) ;; that string is empty string
