based on your stacktrace, here's your bug, fixed in r3839:
from sqlalchemy import *
from sqlalchemy.orm import *
session = scoped_session(sessionmaker(transactional=True,
autoflush=False))
engine = create_engine('postgres://scott:[EMAIL PROTECTED]/test')
session.configure(bind=engine)
session.connection()
session.begin()
session.begin_nested()
session.connection()
session.commit()
session.commit()
