 No, you have to define 
	char* string; /*not 'char**' !*/
and pass address of this variable so it will be set by gtk, i.e.:
                 i = gtk_ctree_node_get_text (GTK_CTREE (ctree1),
	GTK_CTREE_NODE (node), 1, &string);/*note '&string' */

 Also, you are removing the node (and its text) before getting the text for
some unknown reason. If you really need to delete that node,first get text,
than strdup() it, and after that delete it.
