After upgrading to latest version it's gone.
i get 
WARNING: No executable named `fusermount' was found
WARNING: but `fusermount' was specified as a setuid program.
WARNING: No executable named `wodim' was found
WARNING: but `wodim' was specified as a setuid program.

now as well

I really have to add a nix-rebuild test as cron job to keep up to date
