Invalid JDocument Class: Unable to load renderer class RSS

When retrieve RSS from another web with Easy blog we receive this error, we create a account for the staff in order you can see it.

The problem is when the joomla base "mod-feed" retrieve the feeds from the web with Easyblog installed the page doesn´t load and shows that error:

Error displaying the error page: Invalid JDocument Class: Unable to load renderer class

We know this error is caused by EasyBlog because we test the "mod-feed" with another webs feeds and all works fine.

We are check all plugins to find any bug, but any help would be great.

Any idea ? Thanks.
