[Bug 861258] Re: add-apt-repository crashed with ValueError in raw_decode(): No JSON object could be decoded

[Brian Murray]

Another way to recreate the same Traceback reliably is to use a
nonexistent lp user and ppa.  For example:

In [6]: ppa.get_ppa_info_from_lp('curiousgeorge', 'forthemanwiththeyellowhat')
---------------------------------------------------------------------------
ValueError                                Traceback (most recent call last)

     81     curl.close()
     82     lp_page = callback.contents
