Comment 4 for bug 915782

thank you for your help Nicola. I gathered the locks, but in the meanwhile I think that the problem was a failed update before adding OMAP stuff:

i restarted installation from scratch and this time I managed to complete the package update before installing the OMAP-addons and anything worked fine this time.

i think my problem is that i'm not acquainted to the actual gnome desktop and the description in text form on seems to be outdated for me, while the screenshot on the same page is actual.
