[Plugin: WordPress SEO by Yoast] Wrong category permalinks

WordPress version: 3.4.2
WordPress SEO version: 1.2.8.7

I did this: Updating WordPress from 3.4.1 to 3.4.2 and updating the plugin

After that, the category permalinks in my main menu are like this:

http://www.soapfever.de/http/www.soapfever.de/vorschau-alles-was-zaehlt

instead of

http://www.soapfever.de/vorschau-alles-was-zaehlt

Before updating I had another problem: When I added a new category all categories lead to Page not found. Resolving this I had to deactivate the first item in the WordPress SEO Permalinks options, saving, activating again, saving. Then it worked fine again.

Please help 🙂
