I can't open links neither in Okular, MuPDF nor xpdf

Is it a bug in viewers or a property that if I click a link in a pdf, nothing happens in Okular and MuPDF outputs "Couldn't get a file descriptor referring to the console"? xPDF outputs

I thought that they will open the WWW-browser. Here is my test file: (I know it is silly to use the package Finnish babel in English document but I just made a quick test file for to demostrate.)
