[Grok-dev] a mystery ZODB breaking dependency issue

[Martijn Faassen]

Hey,

A few times I've seen old ZODB's break. When I go to 
http://localhost:8080, I get an exception as below (and a System Error).

This just happened when I started using the trunk. I suspect it has to 
do with some version requirement somewhere that changed at some point, 
possibly now using an older version than before.

We can't afford to break ZODBs between Grok versions, so we need to hunt 
this one down and fix it. The first step will be to reproduce this. I'll 
the very least create a copy of this symptomatic ZODB I have now (which 
has some custom application installed so I can't easily share it; we 
need a smaller example).

Please help!

Regards,

Martijn
