Testing ssl-bump-server-first with an upstream proxy

I'm currently testing the SSL bump-server-first functionality in Squid
3.3.0.1-20121122-r12391. I have an upstream proxy with "never-direct
allow all" set (the reasons for this are slightly convoluted :).

When making a bumped request, Squid bombs with:
2012/11/22 17:53:57 kid1| assertion failed: forward.cc:769: "peer->use_ssl"

The post at
http://www.squid-cache.org/mail-archive/squid-dev/201206/0089.html says:
"Allow bumping of CONNECT requests without allow-direct set on http_port.
Previously, that flag was required to allow bumped requests to go direct
because they were (and, sometimes, still are) considered "accelerated"."

So I assume this is supposed to work?
