I can't seem to reproduce this here. I've tried both python 2.4.5 and
2.5.2 using beautifulsoup 3.0.7. I also used the sample html attached in
that email as well part of the code that is supposed to cause the
problem, and I can also run pickle on the body's contents without
getting a RuntimeError.

Any chance you can retry it ? And if you do reproduce it then include
the instructions here instead of pointing to a mail list, please.
