This is a rare error due to multiple inheritance conflicts (see
http://www.python.org/download/releases/2.3/mro). It happens at class
definition time.  Where is the class httperror_seek_wrapper? Could you
provide module and line number? Which version of twill are you using?
I don't find it in my twill installation.
