Hi,
currently one gets some g_critical() when using an element that is based on
GstAudioFilter and GST_DEBUG.

GST_DEBUG=equalizer:5 gst-launch-0.10 audiotestsrc ! audioconvert !
equalizer-nbands ! fakesink
[...]
(gst-launch-0.10:17495): GStreamer-CRITICAL **: gst_debug_log_valist: assertion
`category != NULL' failed
[...]

This is caused by GstAudioFilter using gst_ring_buffer_parse_caps() without
having called gst_ring_buffer_get_type() in some way.
gst_ring_buffer_parse_caps() uses the ringbuffer debug category which is first
initialized when calling gst_ring_buffer_get_type().

Attached patch fixes this and should be committed right after release if nobody
disagrees.
