Absolutely nothing interesting out of `tcpdump -n -e -ttt -i pflog0`
Only a bunch of blocks for rule "0":

I've found this in /var/log/debug.log:
../..
Aug 1 14:00:01 boleskine pflogd[410]: [priv]: msg PRIV_OPEN_LOG =20
received
Aug 1 16:00:02 boleskine pflogd[410]: [priv]: msg PRIV_OPEN_LOG =20
received
../..
But I believe it's not related to my problem at all.
