We are using facebook comments on our site, using fb_social-6.x-2.0-beta4.

We are getting a lot of the following error:

Invalid argument supplied for foreach() in /home/coolthings/public_html/sites/all/modules/fb_social/plugins/fb_plugin/comments.inc on line 304

It isn't a big deal, but it is annoying. I've patched it here, it would be great if it was fixed in the real version too. Thanks!
