Looking at the phonon-gstreamer code shows that the snapshot functionality in gstreamer is only available when compiled against at least 0.10.31. Do you have that or a newer version installed (look at /usr/include/gstreamer-0.10/gst/pbutils/gstpluginsbaseversion.h)?

I use phonon from master/kdesupport.
