Browse source 
Original commit message from CVS:
* gst/gstelement.c: (gst_element_error_full):
make elements try to recursively change state to PAUSED on all
parents after an error to suppress ensuing warnings
* gst/parse/grammar.y:
make it check if it was able to sync the state, and throw an error
if not, so stuff like
oggdemux ! vorbisdec ! osssink gets caught
