I just finished testing with 3.12, and I'm still seeing the same issue.
This is actually a bit strange to me, because, when I tested with
3.12-rc5 a while back, everything seemed to be ok (see previoues e-mail
in this thread, to Bob Liu).  I guess, embarrasingly enough, I must have
been playing with a screwed up config that day, and managed to somehow
avoid the problem...  Either way, it appears that we still have a
problem here.

I'll poke around a bit more on this in the next few days and see if I
can come up with any more information.  In the meantime, let me know if
you have any other suggestions.

Thanks,
