If you have failed to do that than try my steps:

0. sudo gainroot
1. in Xterm do this: apt-get install --reinstall ogg-support=1.0.5
2. if you don't get a notice for apt-get autoremove like 'kolos' said to remove these packages gstreamer0.10-av, gstreamer0.10-maemo-xiph and tracker-extractor-flac
3. than you need to remove them manually from FAM in Advanced category.

4. I think this is the simplest way how to fix it.
