The man page of pfdCleanTree says that you can send a pointer to your own
function which decides if the current node should be cleaned up or not.

I have tried using this feature of pfdCleanTree, but for some reason,
my function which is passed a pfuTraverser type from pfdCleanTree, doesn't
contain a valid "node" field of pfuTraverser. It is always NULL. Hence I
can't do any comparisons for node cleanup. Looking at the code of
pfdCleanTree it looks like the traverser is not being properly initialized
to contain a valid "node" field before being passed to the user supplied
function. I guess this is what is causing the problem.

Since this is an unsupported tool, we need to correct it ourselves.

Good luck
