Usually, you should avoid try ... except with unrestricted exception
catching. But here, it would be justified.

I would probably even remove the offending entry from the registry...

   ZSQLMethods has nothing to do with PTKBase. When I try to 
 access any

 You know the custom classes you can use in the ZSQL Advanced tab?
 You can use ZClasses to implement such classes.
 
 The method Shared.DC.ZRDB.DA.DA.manage_product_zclass_info
 runs through all ZClasses and tries to build a list of
 ZClasses that can be used for this purpose.
 
 Thereby, it hits a ZClass that is dependent on a product that 
 is no longer
 installed.
 
 Your options:
 
   *  find the ZClass that produces the problem and delete it.
 
  It is probably an old Portal Toolkit ZClass.

I'm pretty sure that no longer exists either. Something must be wrong with
the code that cleans out this registry. This email shows the problem quite
clearly
http://mail.python.org/pipermail/zope/2001-August/097435.html 

If I could somehow readd the appropriate classes and then delete them so it
removes the classes properly then that might clear it out but I havn't
managed to do that yet. This registry looks like a real bodgy piece of work.
Shouldn't it use more indirection or be able to refresh itself or something
