Just to correct myself: this isn't entirely true, it's fine to call
_set_state() on a newly-added element in a pad-added callback for
example, but you shouldn't change pipeline state from a streaming
thread.

Without more information it's hard to guess what exactly you're doing
and what's going on. Do you have a short piece of code that reproduces
the problem?
