Comment 10 for bug 1053315

Supposedly phonon-backend-gstreamer cannot be satisfied, so it wants to keep xine except xine can't be kept so it wants to remove all and everything kde including update-manager-kde.

Why backend-gstreamer canot be satisfied is a mystery to me though, from looking at the deps and the apt.log it marked every dependency for installation it appears.

I really think there is a foreign package invovled somewhere.

What happens if you run
sudo apt-get install phonon-backend-gstreamer && sudo apt-get purge phonon-backend-xine
