[Grok-dev] Upgrade problem "type object 'IRole' has no attribute '__iro__'"

[Sebastian Ware]

My problem is that this prevents me from updating my customers project  
without exporting and importing all the data, something that isn't  
very easy at the current state of Grok.

I hope someone can give me some hints on this.
