Problems with mp3 / Phonon

Hi, I've run into a new problem on 13.1 (don't know if specific to that version though).

Some (not all) mp3 files are unable to play in audio players that use Phonon, like Amarok and Dragon. The files play just fine in xine, gxine, mplayer, xmms and audacious so there is nothing wrong with the files. I'm using xine-backend for Phonon so that indicate the problem lies with the layer between xine and Phonon, or Phonon itself, since I can play with normal xine. I tried using gstreamer backend but with that I'm unable to play anything but ogg...

In Amarok I get the error: MPEG::Header::parse() -- Invalid sample rate.

In Dragon I get the error: xine is asking to seek behind the end of the data stream

Would it be possible to upgrade just Phonon or it's xine-backend? Or do I need to upgrade entire KDE then?

I wonder if it is actually taglib that's causing the problems.
MPEG::Header::parse() -- Invalid sample rate. is a common problem with taglib. Taglib does not support all VBR headers.

You can try to remove/edit/regenerate the id3 tags.

For gstreamer you need some extra plugins. SlackBuilds.org has them (bad, ugly)

It does not in fact seem like a fault of taglib. I tried removing any tags and it made no difference. Of course I can also play the files fine in Audacious which also uses taglib.
