[Zope] Crashes after ftp access?

I'm really new to Zope, so please excuse my ignorance. I've been playing around with Zope, and I tried using emacs with angeftp. However, every time I try to connect to the ftp server at 8021, emacs complains that it can't connect. Afterwards, zope dies and I have to restart it again. Has anyone else encountered this? Thanks for any help!
