This is probably a side effect of a change in node.utils.instance_property. I need to figure out what happens

[rnixx]

Should be fixed via https://github.com/bluedynamics/node/commit/0ca2f370600eaa609c856d927f5cd61e2d0481e8

I also spent some love on node.ext.zodb https://github.com/bluedynamics/node.ext.zodb/compare/bb49c158ea...fe63110909

May you be so kind and try again with latest master versions of odict / node / node.exz.zodb ?

If everything is fine I'll drop a release.

works for me
