Kepler is very old, but probably unrelated to CDO issues.
CDO 4.4 is also out of maintenance. Have you tried the same scenario with the just release CDO 4.5?
What database are you using?

You could try the same usage scenario without referential integrity checks. That could gives us some pointers.

I'd need exact steps to follow in order to reproduce the problem ;-(

It would probably be good to set a breakpoint on the line that acquires the null pointer and then step through the code.
Depending on what you find out I might be able to give more advice.
