    ContactSheet: Give user feedback on URL error
    
    If something goes wrong, we give no feedback to the user whatsoever
    (unless they happen to have run Contacts from the terminal, which is
    almost never the case). Show a small notification if something goes
    wrong and add the details for us to debug later.
