conduit 0.3 isn't yet released to Hackage, but here's the patch for when it is. This was actually an incredibly easy fix, which bodes well for the 0.3 migration.
Looks fine. You may merge & release when the time comes, or just send me a nudge and I'll do so =).
OK, I've added it to my ever-increasing list of packages to be released with the next conduit :).
