VerifyError when initializing PicasawebService. #447

I made thing simple to use a PicasaWebService to load a list of user albums

//The error occurred at the first line.
 PicasawebService myService = new PicasawebService("VideoAlbum");
                myService.setUserCredentials("email@blah", "password");

                URL feedUrl = new URL("https://picasaweb.google.com/data/feed/api/user/email@blah?kind=album");
                //URL feedUrl = new URL(String.format("https://picasaweb.google.com/data/feed/api/user/%1$s?kind=album&access=all&token=%2$s", Plus.AccountApi.getAccountName(client), token));

                UserFeed myUserFeed = myService.getFeed(feedUrl, UserFeed.class);
                Log.w("PICASSO", "C " + myUserFeed.getAlbumEntries().size() );
                for (AlbumEntry myAlbum : myUserFeed.getAlbumEntries()) {
                    System.out.println("PICASA ALBUM "+ myAlbum.getTitle().getPlainText());
                }
When one the code I received,
