I see the same thing with vanilla v3.6-rc1, but it worked in my pm-cur branch which has a few fixes that I'm queuing for v3.6-rc. Tracking it down, it seems the revert patch I just sent out[1] fixes this problem, but I'm still a bit puzzled as to why. Can you try v3.6-rc1 + that revert[1] to see if that fixes the problem for you as well?
