I guess this works on all applications of the Gnome/GTK desktop?
Maybe not what the user wants...

Thanks, this sounds good. I was not aware that this "query-tooltip"
handler is involved at all when I only use a simple
gtk_tree_view_set_tooltip_column()
(http://developer.gnome.org/gtk3/stable/GtkTreeView.html#gtk-tree-view-set-tooltip-column)

I will test it.
