We got an issue in Swfdec where gstreamer returns an invalid buffer size when
decoding certain mp3 file, making things crash and burn.

Trying to figure out what's wrong, the following valgrind warning seemed most
suspicious:

==799== Conditional jump or move depends on uninitialised value(s)
==799==    at 0x9944AC4: gst_audio_quantize_quantize_signed_tpdf_none
(gstaudioquantize.c:314)
==799==    by 0x993FE94: audio_convert_convert (audioconvert.c:587)
==799==    by 0x993D4BA: gst_audio_convert_transform (gstaudioconvert.c:981)
==799==    by 0x8212C02: gst_base_transform_handle_buffer
(gstbasetransform.c:1471)

This is from running:
gst-launch-0.10 -v filesrc location=682.mp3 ! mad ! audioresample !
audioconvert !
'audio/x-raw-int,endianness=byte_order,signed=(boolean)true,width=16,depth=16,rate=44100,channels=2'
! fakesink

My gstreamer version is 0.10.18 from Ubuntu Hardy

I will upload the full log and the mp3 file
