gnome-sound-recorder, build from gnome-2.4 series approx Sept 24:

To reproduce:

* Press 'record', record some sound (I recorded from a CD, 3-4 seconds worth)
* Press 'Play'; sound plays back as expected.
* Press 'Play' again, nothing happens.

after playing once, the sound file seems to be lost.  You can't record over
it either, i.e. pressing 'Record' again followed by 'Play' doesn't seem to
work either. 

If you do this in the console, gstreamer reports:

GStreamer-WARNING **: abnormal clock request diff: ABS(6110358641) > 2000000000

repeatedly.

so maybe this should be transferred to gstreamer? 

Here's the initial gnome-sound-recorder console output, plus the first
gstreamer error message:

INFO (16841: 0) Initializing GStreamer Core Library version 0.6.3

(gnome-sound-recorder:16841): GStreamer-WARNING **: abnormal clock request

I will attach my registry.xml file.
