Multiple selections does in fact work in your example, but one has to
hold down the ctrl (or shift) key while selecting (which is in
accordance with the Gnome HIG). The list example in testgtk.c has a
slightly different (probably more intuitive) behavior, but is based on
the deprecated GtkList widget. I haven't found any way to get the same
behavior with GtkTreeView.

This was caused by errors in the definition of the tree-view slot for
tree-selection, but should work now.
