--- Comment #3 from Sebastian Dröge (slomo) <slomo at coaxion.net> ---
Can also happen in the following scenario:
1) streaming thread of some element is waiting on a pad probe (stream lock)
2) gst_element_send_event() doing a SEEK, waiting for streaming thread to shut
down (state lock -> stream lock)
3) gst_element_set_state() (state lock)

3) *would* unblock the pad, which would unblock the streaming thread and make
everything happy... if there wasn't the state lock.
