Your problem is not in the catalog.

If the "KeyError: 'validate'" really comes from the code
snippet above, then you have a "DTMLMethod" with a very
strange "__dict__". A normal dict would not raise
a "KeyError: 'validate'", even when 'validate' indeed does not exist.


If fear, this problem is big enough that debugging is necessary.

No (there is no limit on the catalog size. It may just get a bit slower).

Unlikely. The code (as least the quoted one) should work...
