I had to install python-sip4_4.7.9-1_i386.deb to actually make it work. Before
that my whole python-qt4 installation was broken, should be so for others too.
Now, when I follow simple steps:
from PyQt4.phonon import Phonon
mediaObject = Phonon.createPlayer(Phonon.NotificationCategory,
Phonon.MediaSource("local.mp3"))
mediaObject.play()
I get the following lines on stdout:

I don't get any actual sound output. It seems like Phonon is probing all
available sound cards and failing.
And indeed qtconfig-qt4 is grayed out in the Phonon configuration section and
says "Phonon GStreamer backend is not available".
KDE Phonon though works, is that a packaging problem? Do I need other packages
installed?
Should I open a new bug report?
Please CC me in replies.
