    properties-dialog: Be more forgiving of unknown nmm:flash values
    
    It's been a year and we still don't know what exactly happened. Who
    knows what is out there in the wild? So, instead of aborting let's try
    to handle this more elegantly.
    
    Keep the warning, remove the assertion and show an empty label.
