I've done my best to file a bug report but the LaunchPad website defeated me.
Was directed to go to https://wiki.ubuntu.com/Releases to check for existing bugs and I got this error message about that website:-
Internal Server Error

Please contact the server administrator, webmaster@xxxxxxxxxx and inform them of the time the error occurred, and anything you might have done that may have caused the error.
