Comment (by asn):

 OK, did some log digging to get answers to these questions.

 Yes, I was using bridges.

 I think this error occured when I switched from using 1 private bridge, to
 using the default tor browser bridges. I did the switch using the tor
 browser options dialog, so I assume that it HUPed Tor when the change
 happened.

 As you can see in the log above, my private bridge (`$160228DC...`) got
 marked as non-filtered (because it was not on torrc anymore), and the
 regular tor browser bridges were about to get sampled, and then the error
 occured.
