You don't say which thread you're calling this from... As far as
gstreamer is concerned, there's nothing special about your mainloop
thread - the only threads that are special to gstreamer are its own
streaming threads - the threads that it creates itself. 

You are not - ever - allowed to call gst_element_set_state() from one of
these streaming threads. I suspect this is what you're doing, and that's
why it's deadlocking.
