FLAC playback with Juk

[mgp]

Hi,
I can't play FLAC files with Juk. Reading through this bug report:

There are two requirements for file playback. Playback has to be supported by
the backend (either aRts, gstreamer, or aKode), and the file type has to be
supported by taglib.

Apparently taglib works for me because I can load flac files and see their titles, etc. But when I hit "play" nothing happens. I only have gstreamer for backend and of course multimedia/gstreamer-plugins-good which, according to the documentation, supports FLAC (en|de)coding.
Does anyone else have this problem? And does anyone have a solution?

This is what I have:

Juk 3.6.3
KDE 4.6.5
flac 1.2.1
gstreamer 0.10.35
gstreamer-plugins-good 0.10.30
phonon-gstreamer 4.5.1
