[Zope] Zope Session error (has: Unidentified Zope error)

[kepes.krisztian]

Hi !

I get the error message again in Zope 2.7.1.

Seems to be session error. Sessionmanager is say that "neworexisiting" 
key is not found, and make errors in transience module.

The event.log is say that:

So: I not get that problem when I working with my local server, and I 
use Mozilla. But when I try to show anything to my boss with his IE, the 
Zope is "crashed". I say crashed, because I must restart it to work it 
again...
(And the too many computer user use IE... :-( )

The 2.7.3b is buggy, so I don't have any chance, only downgrade.

Please help me:
Is the 2.6.4, or 2.6.3 is have this problem ? Is 2.6.4RC2  working good ?
I must downgrade, but I don't know, what the version I choose to 
eliminate these session errors.

Thanx for help:
