It seems that you have outdated manual which describes
mgd_walk_xxx_tree() functions in wrong way. Please download current
version of manual from
http://www.midgard-project.org/~emiliano/docs/
In brief: mgd_walk_xxx_tree() doesn't return anything, it calls user-defined
function (UDF) instead. Also it doesn't pass objects' IDs to UDF in
some definitive order, so your code must do ordering if needed.
