You'll get this warning whenever a non-XView object handle is passed
handed to a generic xv_*() function.  Sometimes these errors occur when
your code uses a value returned from xv_create/get/find in another
xv_*() call without first checking to see if the value is either NULL
or XV_ERROR.  To find this place where the bad object value is being
passed, you'll need to place a break point at the entry point to 
xv_error() and then look at the stack trace.
