Hi Kriesi, and many compliments for your great programming !!!
Devin told me that you being informed about my problem. It's just a matter of coherence. Years ago, you made a newscast.xml file (unfortunely corrupted) and published for your customers. If you are an elite programmer (like I and ThemeForest believe) please give us an operating version (otherwise, it makes no sense to publish a non-functional version). It's not a problem for you to build an XML file with your demo data, like you made for other WP themes.
In summary, why publish a corrupted version instead of a full version? You're a professional, not a beginner, so if you publish something that's unfortunely wrong (it may happen) please publish the right version. Otherwise, please don't publish anything :)
Please find following the corrupted XML file:
