Hi folks, 
 
I've got a pipeline like this: 
 
 x---------------------------------------- ScAudioPlay thread -----------x 
 |                                                                       | 
 |                                                                       | 
 | x--------- ScAudioDecode thread -----------x                          | 
 | | src ! spider ! audioconvert ! audioscale | ! queue ! vol ! audiosink| 
 | x------------------------------------------x                          | 
 |                                                                       | 
 x-----------------------------------------------------------------------x 
 
The ScAudioDecode part is re-created for every new song to be played. 
 
This worked fine with all previous 0.8.x versions, but now suddenly I get this 
when changing songs (as far as I can see when changing from an .ogg to 
an .mp3, but there might be other cases as well):

-------------------- 
 
sometimes the warnings look like this: 
 
(scentric:2802): GStreamer-CRITICAL **: file gstcaps.c: line 203 
(gst_caps_copy): assertion `GST_IS_CAPS (caps)' failed 
 
(scentric:2802): GStreamer-CRITICAL **: pad queue:sink returned NULL caps from
