Short description of error
PulseAudio randomly asserts when doing background renders, presumably due to an issue in D10580: Add PulseAudio.

Assertion 'q->length == 0' failed at pulsecore/queue.c:63, function pa_queue_free(). Aborting.

Exact steps for others to reproduce the error
This repeats a simple background render and stops on error, almost always hits the error within the first 10 renders here.
