[ZODB-Dev] Re: Relstorage

[Ben Mason]

We're currently benchmarking RelStorage to see if it's a viable alternative
to ZEO.

We've come across the following problem: When trying to revert to an old
version of a page, we get a unicode error:

Traceback (innermost last):
  Module ZPublisher.Publish, line 119, in publish

All that has been done here is... Click Edit on the front page of a clean
Plone site, click Save. Go to the History tab and click on 'Revert to this
revision'

This doesn't happen if we're using the traditional Data.fs way of storing
data.

Anyone know what is going on?

Thanks
