In 0.8.1 there were no type arguments on Gdk.DragContext.targets... they
were added on 2010-07-17 [1], but 0.8.1 was released on 2010-04-21.
Updating Vala is probably not a bad idea (lots of bugs like this have
been fixed in the past 17 months), but you should be able to work around
this issue by doing something like this:
unowned GLib.List<Gdk.Atom> targets =
(GLib.List<Gdk.Atom>) (context.targets);
Gdk.Atom target_type = targets.nth_data (0);
Or, if you want to avoid the extra variable:
Gdk.Atom target_type =
((GLib.List<Gdk.Atom>) (context.targets)).nth_data (0);
