If you've got a crash it'll likely be because what you are doing
somewhere is buggy, perhaps an assumption somewhere.  Overriding
addChild/insertChild() won't cause a crash if done properly.

In the case of paged databases nodes are added and removed, the later
can cause problems such as if your code just uses C pointers to these
nodes assuming that they'll always be around.

I can't say what might have caused the crash for you as I know nothing
about the code you've written or what the crash is, or exactly what
circumstances it happens in.

You'll have a debugger, your have your code, your data, you're the
person best placed to debug it.

Robert.
