I've also come accross this same problem with the "tree-select-row" signal of
the GtkCTree. Specifically, when the signal is called, I call a function to
get text from the row, like so:
<code>
void CTreeTreeSelectRow(GtkCTree *folders, GList *nodeList, gpointer object){
        char *text;
        gtk_ctree_node_get_text(folders, GTK_CTREE_NODE(node), 0, &text);
</code>
This call returns false, and 'text' is not filled. (This error showed up in
1.2.8 and 1.2.10)
Any thoughts anybody?
