Overview Description:
gst_element_query makes vorbisfile crash when switching from .ogg file to .mp3



Steps to Reproduce: 

1) I have the following pipeline (a GstThread):
   gnomevfssrc ! spider ! artsdsink
2) playback a vorbis file
3) change to a mp3 file (NULL, set "location", PLAYING)
4) query the sink element (making sure that the thread is in
GST_STATE_PLAYING again)



Actual Results: 

The application crashes (segfault), from vorbisfile_get_type() (???)
Backtrace below.



Expected Results: 

More gracefull handling in vorbisfile (just returning FALSE from the
gst_element_query function). Maybe even not going into vorbisfile at all??



Additional Information:

It also crashes when switching from ogg -> ogg, but there is already a
report on that.



Backtrace:
 
Program received signal SIGSEGV, Segmentation fault.

player_timeout_func is a function to periodically update a progress bar.

spider isn't reusable.  put in a new spider instead.
