g_tree_traverse on an empty GTree

[Simon K}gedal <sika8225 csd uu se>]

Hi,                                                                       

I want to be able to run g_tree_traverse on a GTree that is empty
(but of course created, with g_tree_new). But line 167 in gtree.c
complains on this. It says:                                      

g_return_if_fail (rtree->root != NULL);

I'd rather have it just:

if (!rtree->root)
  return;        

Or is there something illogical with being able to do that? Otherwise,
I'll have to check myself if the tree is empty, and how do I do that  
without using g_tree_nnodes (tree) ?                                

Thanks,
