XtUnmanageChild - intermittent crashes

I am using an interface for multiple situations which calls for either
Managing or Unmanaging certain widgets. I am having problems with
some generic the generic 'Widget' which is what I manage and
unmanage. I am using XtManageChild & XtUnmanageChild.

Some times this works but most often it crashes. Sometimes saying
"Warning: Null child found in argument list to unmanage".

This is only reported sometimes and I know these widgets are not NULL.

Any help would be great.

Thanks in advance
Bender

I assume you've tried:

if (widget != NULL) {
XtUnmanageChild(widget);
} else {
fprintf(stderr, "Oops! Widget to unmanage is NULL...\n");
}

It's hard to diagnose the problem without a sample of your offending
code.
