embed.js 404 in Webmaster Tools

Hi,
I wanted to reopen the following discussion:
http://ww.wp.xz.cn/support/topic/plugin-disqus-comment-system-crawl-errors-with-plugin?replies=7
There is also a github pull request on this (solved):
https://github.com/disqus/disqus-wordpress/pull/24
Both mark this as resolved, but I just started receiving these errors in my WebMaster Tools:
404 for http://www.baeldung.com/embed.js?pname=wordpress&pver=2.74
Any idea why this is? Is this a recent regression?
Thanks.
Eugen.
