[Zope] Zope not starting after VaryTag install

[Didier Georgieff]

Hello,

Just after installing VaryTag, Zope (2-1-6)  restart fine, but when i 
try to connect to my zope adress, i got an error (traceback further).

So i stopped Zope, removed the VaryTag product, and the error is 
still here.
So, i don't have access to my manage screen to remove the 
VaryTag traces or anything slse.

Any quick tip would help me a lot, an avoid killing myself for 
loosing access to my site ;-))

Thanks in advance
