[Zope] Zope broken - can't restart

[Dennis Godfrey]

I added a package to the Products directory today. When
I tried to restart, I got a Proxy error and things went
downhill quickly.

We are using debian testing (running zope on port 9673)
Zope 2.6.2

Starting it and restarting it give differing errors:

collab:/var/log/zope/default# /etc/init.d/zope start
Starting Zope instance default...
  failed: coercing to Unicode: need string or buffer, NoneType found
  Waiting instances in late: done.
default: start: coercing to Unicode: need string or buffer, NoneType found

collab:/var/log/zope/default# /etc/init.d/zope restart
Restarting Zope instance default...
  failed: 'NoneType' object has no attribute 'rfind'
  Waiting instances in late: done.
default: restart: 'NoneType' object has no attribute 'rfind'

Does anyone know what "'NoneType' object has no attribute 'rfind'"
means? How about "coercing to Unicode: need string or buffer, NoneType
found"?

Can anyone give me a clue as to how I can get zope running again?
Thanks!
