Daemon debug log of git master with "pacat --rate=5"

Pulseaudio daemon aborts when a client tries to play back audio at sample rate
range 1Hz..5Hz.

The following commandline triggers the issue on 4.0 and on git master:
$ echo foobar | pacat --rate=1

The error is:
E: [null-sink] sink-input.c: Assertion 'tchunk.length > 0' failed at
pulsecore/sink-input.c:933, function pa_sink_input_peek(). Aborting.

This happens on both null-sink and on alsa-sink.

Debug log is attached (null-sink case).
