I did a setup with a couple of machines yesterday (6.2-RC2 and 6.2-RELEASE) that demonstrated the problem. On my 6-STABLE system (which appears to be working fine), I still have the change from 1.48.2.16, I only backed out .15 and .14. I didn't try my diff on the 6.2-RC2 and 6.2-RELEASE machines yet. Hmmm...I was looking for that bug report before, but I couldn't find it. It's not clear to me how 1.48.2.16 is involved...hmmm...
