Citing http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeSelection.html#gtk-tree-selection-get-selected-rows:
Returns: A GList containing a GtkTreePath for each selected row.
In other words, the list consists of GtkTreePaths, not
ints, so you print the pointer to the GtkTreePath (casted to
an int) instead of the row number. The reference also
describes how to free the returned list properly.
