    fixup! c-e: show tooltip with validation error
    
    Restore printing the validation error, but as message, not warning.
    It might still be useful for debugging.
    
    Also, we might want to suggest to a user that he looks at stdout for
    messages -- which would also semi-work with prevous version (although
    the message being less helpfull).
