Problem description:
Airplay is not working. XBMC quits to login. no logfile entry is written after stopping xbmc.

How to reproduce:
using IPAD2 with IOS 7.1.1 - start playing audio and switch to AirPlay on xbian.

fresh install from scratch with image from xbian.org with all updates works either. (btw: image should be renewed - takes hours to update, still has the python update problem. would help new users to start...)

any clues?
