Trying to get property of non-object: $post->post_modified_gmt;

Hi,

We have a pretty popular site, and Akismet throws several hundred ErrorExceptions per day for this:

ErrorException: Trying to get property of non-object
#13 /srv/www/htdocs/SITE.com/public/wp-content/plugins/akismet/class.akismet.php(174): handleError

#1 wp-includes/class-wp-xmlrpc-server.php(197): serve_request

The issue is here: akismet/class.akismet.php:174:

$comment[ 'comment_post_modified_gmt' ] = $post->post_modified_gmt;

$post is null. I’m not sure exactly why, but could you add a check for null here?

I’m using Akismet 3.3, which is the latest version right now.

Thanks.
