    wizard: Don't hang on failure to handle a URL
    
    Boxes would just hang in wizard's preparation stage if you pass a path
    to a file on a locally mounted remote share (e.g SMB). Although the real
    solution is to be able to handle those, we should have this in place
    just in case this codepath is walked for some other reason.
