Do you have multiple threads by any chance? I've seen that kind of an
assertion with code that accessed the mainloop from multiple threads.
libpulse is not thread-safe, so accessing libpulse objects from
multiple threads is not supported (unless you yourself implement the
necessary locking to make it safe).
