Errors when video has been deleted

Hi. I'm creating a site that had lots of Youtube videos that where ported to drupal as standard nodes. I created a custom type called Video and used the Youtube field module to store the references to the corresponding video. All this was done programatically so the process didn't grab the thumbnail from the video (the poster image) when nodes where created.

This is not a problem since the thumbnail is created when the video is shown in a view I created to list them. However, there are old videos that have been deleted from Youtube, so when the module tries to get the info about them in order to create the thumbnail I'm getting this error messages for each video not found, plus a broken image file stored in the sites/default/files folder:

Notice: Undefined property: stdClass::$data en youtube_get_remote_image() (line 62 of /www/sites/all/modules/youtube/youtube.inc).
Notice: Trying to get property of non-object en youtube_get_remote_image() (line 62 of /www/sites/all/modules/youtube/youtube.inc).
Notice: Trying to get property of non-object en youtube_get_remote_image() (line 62 of /www/sites/all/modules/youtube/youtube.inc).
Notice: Undefined property: stdClass::$data en youtube_get_remote_image() (line 77 of /www/sites/all/modules/youtube/youtube.inc).

The pertinent code is in the youtube_get_remote_image() function:

$result = drupal_http_request($url);
$data = json_decode($result->data);
// Get the high quality default thumbnail.
$src = $data->data->thumbnail->hqDefault;

The error is generated because there's no validation when $data is retrieved and, if no video was found, the variable is empty. It's trivial to fix it by adding a check as follow:

$result = drupal_http_request($url);
$data = json_decode($result->data);
if (!isset($data->data)) {
    //return FALSE;
 }
// Get the high quality default thumbnail.
$src = $data->data->thumbnail->hqDefault;

Plus, this makes the module to create a nice default poster image.

Best regards.
