The README.developer indicates that it is ok to call the proto_tree_add_xxx funcs when the tree is null. If I do this howver, I get a core in proto.c line 2078 alloc_field_info. Its doing: 

if(!PTREE_DATA(tree)->visible) {
	FI_SET_FLAG(fi, FI_HIDDEN);
}

Shouldn't there be test for tree being NULL?
Or should I avoid doing any proto_tree_add_xxx with a null tree. Doing so complicates my code a fair bit because I want to set the COL_INFO with some data deep within my packet. 

Thanks,

	Andy
