[Zope] Product->refresh broken in zope-2.4.3?

[Sven Rudolph]

Hello all!

After "refreshing" my product I can't create new instances of my product any more. I get the following error message:
'Object of type "None" is not callable'
This happens even if I didn't change anything in my source code. Just clicking the "refresh" button is enough.
When I restart the sever everything works fine again.

This behaviour is new in zope-2.4.3 (I updated from 2.4.1)
Is this a known bug? Must I downgrade again to 2.4.1?

Thanks in advance

Sven
