texlive 2013, arabxetex, polyglossia

Hello everybody,

When I try to write vocalized Arabic text using arabxetex and/or polyglossia, the result is disjointed: all consonants are represented in their isolate form, every letter is separate, no ligatures. When I remove the vocal signs, the consonants are represented correctly.

I work with openSuse 13.1 and texlive 2013. My editor is GNU/emacs with Auctex. Has anyone had similar problems? Solutions?
