To me it looks like the pad is blocked. We had a similar issue where we would
handle a "pad-added" signal async, by blocking the pad and marshaling the
signal onto the MainContext, but if the state-change was spun after the pad was
blocked, but before the signal, we would get a callstack like this one...

I don´t know playbin2, but if it uses pad-blocking anywhere, and the
state-change are able to get in between the blocking and the unblocking, you
could get something similar to this callstack.
