On node save the notice
Notice: getimagesize() [function.getimagesize]: Read error! in image_gd_get_info() (line 349 of C:\wamp\www\store\modules\system\image.gd.inc) is created and the thumbnail image does not show.
I have attached four images from the debugging program that include the variable values. The first two images, media_youtube_bug1.jpg and media_youtube_bug2.jpg are from when the youtube link is added through the media dialog and the user is returned to the node edit or node create page. The last two images, media_youtube_bug3.jpg and media_youtube_bug4.jpg, are from when the user clicks the save button on the node edit or node create form. I have no other information than the site being relatively vanilla and I'm using the latest dev version of Media and Media Youtube modules.
