Re: [Zope] Is data.fs corrupted?

Maybe it's a Zope-level rather than ZODB level problem? Maybe some of the ZClass machinery or product registration machinery is screwing things up?

This is possible. Maybe even likely.

Given that people have reported this from more than one product now, I'd be inclined to think it's not random bits of bad code in products. Maybe there's a method/pattern which used to be okay/recommended which is now causing problems?

Some of the product registration code has been overhauled by Tres Seaver lately.. I wonder if he spotted anything that would have caused something like this.
