[Zope] Error adding ZClass instance

[Michael Schulz]

Hi,

i have a made a product with a zclass in zope 2.3.4, created with the
zclass constructor methods. It worked fine. Now we've upgraded to zope
2.4.3. When i try to add an instance of this product i get the following
error:

<!--

I have tried exporting and reimporting the product, but no change in
behaviour.

The weird thing is, that there are some subfolders where adding an
instance of this product works without problems. I have checked the
permissions and these subfolders have no special settings. If it had to
do with permission I would expect any kind of unauthorized error or sth
related instead of this name error problem, or am i wrong?

I have noticed that other Zopers have experienced this behaviour too,
did you solve the problem? Anybody else who knows why this is happening?

TIA, Michael
