pulseaudio -vv output

This assertion occured when playing an audio stream and starting pavucontrol
halfway through the stream. I happened to have pulseaudio running with -vv, so
I'm attaching that log output. I unfortunately don't have a stacktrace, nor
have I succeeded in reproducing this particular assert.

This assertion was observed running pulseaudio 2.0 from Debian (2.0-3).

Here's the tail of the log:
