Disqus Comment System – Http error when changing a post status

Hello there,

I have installed Disqus Comment System plugin and it’s working fine, except when I try to change the status of a post.
So, when I try to change the status of a published post to drafted, I get the following Http error:

Warning: fopen(http://disqus.com/api/update_thread/): failed to open stream: HTTP request failed! HTTP/1.1 400 BAD REQUEST in /usr/local/www/pythonbeginner.loc/wp-content/plugins/disqus-comment-system/lib/api/disqus/url.php on line 207

Warning: Cannot modify header information - headers already sent by (output started at /usr/local/www/pythonbeginner.loc/wp-content/plugins/disqus-comment-system/lib/api/disqus/url.php:207) in /usr/local/www/pythonbeginner.loc/wp-admin/post.php on line 233

Is it a bug I should report to Disqus team?
Please note that the status of the post is changing correctely afterward.
