 Just thinking again about you and your problems - I found that your code
for ctree seems to be incorrect. For GtkCList (which is parent of CTree), 
	GTK_LIST (list1)->selection->data
is the _index_ of selected row (or -1 if nothing selected).
To get CTREE node, you have to use 

  GtkCTreeNode* gtk_ctree_node_nth            (GtkCTree *ctree,
                                               guint row);
And do what you need to do with that node (get text).
Could you check whether all this works? Sorry for so late solution..

 As for using - gtklist - it's deprecated and seems it will be absent in next
major version of gtk, so stick to gtkclist (if you still have to switch after
trying what I said above).
 In case of clist, after you have the index of the row, just call

gint        gtk_clist_get_text              (GtkCList *clist,
                                             gint row,
                                             gint column,
                                             gchar **text);
 To get the text.
