Description:
I got this error from gnomebaker:

Internal GStreamer error: pad problem.  File a bug.gstpad.c(2562): gst_pad_set_explicit_caps: /gnomebaker-convert-to-wav-pipeline/decoder/mad18:

serpentine has the same problem:

A friend of me sent me detailed information, that the gstreamer pipeline
didn't work, but I dont have his IM-Message here.

I reported this bug also for gstreamer0.8, but their was no reaction.

This bug is a showstopper, because audio burning is a must-feature.
