I am having the same problem. I have also deactivated everything else and determined it is this Wordpress-SEO that is doing it. Updating permalinks doesn't fix it, and it also does it with the 2012 Theme and no other plug-ins active. It is doing it in the category archives on my blog, but the tags work ok. I currently have it disabled so that it doesn't mess up my blog. Looking forward to hearing some resolution.
