Ah, got it. That's because GtkTreeView (actually GtkTreeSelection)
doesn't emit "changed" for the selection when one of the selected rows
changes, while ExoIconView does emit "selection-changed" there. The
context menu is only updated when the selection changes, so to update
the context menu in the detailed list view, you'll need to
unselect/select the row (or any other action that causes a "changed"
signal to be emitted on the selection). This could be changed in
GtkTreeView, just file a bug report to Gtk+; on the other hand it's not
really a major issue IMHO.
