This may be fixed in Zope 2.10.4; there are several fixes in that release that help with ZEO and packages-as-products.

"Please check if the problem persists and if it is reproducable"
--> Yes it is, I've tried it on two different servers with Zope 2.9.5 and 2.9.7.

I've just tried to remove Five and indeed I don't have the error anymore.

 Status: Pending => Accepted

 Supporters added: rocky

This is a bug in the "python package as products" support currently
within Five:  it is trying to commit transactions within the
'initialize' call of Five, which *must not happen.*

Rocky, can you work out out to preserve the real feature without
opening a new database connection?

>I have a Plone site that works well without using ZEO.
>Yet since I've installed ZEO I've got an assertion error message when I try to add plone pages in my folder.
I've tested it on two different servers with Zope 2.9.5 and I always get this error. If I keep the exact same config but remove the ZEO, it works again.

>I've read that someone had a similar error using Zope 3 (http://mail.zope.org/pipermail/zope3-users/2006-July/003833.html). I've tried like him to change at line 367 of lib/python/ZEO/cache.py the "cur_tid < tid" to "cur_tid <= tid" and now i don't have the assertionError anymore.
>But I wonder if this is a reliable change.
