General Pagination and Taxonomy List Problem?

Since I updated to GRAV 1.0.5 there seems to be a problem with the baseurl for Pagination and the Taxonomy List in skeleton PINPRESS. When the page Blog is used as the homepage, the pagination url seems to be wrong: /grav/page:2 instead of /grav/blog/page:2.
And also the Taxonomy List URL's are wrong: /grav/tag:support instead of /grav/blog/tag:support
There seems to be the same error in the skeletons: BLOG SITE and STRIPED. Maybe a general bug of {baseurl}? Or what am I doing wrong? 2015-12-24 10_0414-Home Oswald Web

Sorry folks! Got it! It was the supported language, which was not set!
