[Vala] Gtk.RecentFilterInfo and some interface issues.

[Erick Pérez Castellanos <erick red gmail com>]

Hi:

I have two issues right now coding in vala:

First:
I'm using Gtk.RecentFilterInfo, and i got this:

Gtk.RecentFilterInfo a = new Gtk.RecentFilterInfo();
error: 'Gtk.RecentFilterInfo' does not have a default constructor

and my question is how to instantiate that. Now I've found that in Gtk c 
code GtkRecentFilterInfo is just a struct, and in gtk+-2.0.vapi is declared 
as a class (annotated with Compact modifier). Could this be a bug ?
If it is not, please show me how to use it.
(BTW, when I manager to hack the compiler using 
GLib.Object.new(typeof(Gtk.RecentFilterInfo)) then gcc give me an error when 
looking for gtk_recent_filter_info_free() ("undefined reference") and that's 
logical cause there's no such a function in Gtk library.

Second:
In Gtk.RecentChooser interface there are properties: i.e.: limit not 
declared abstract, and I suppose i don't have to instantiate those in my 
class (which is implementing the interface), but when I'm using that 
property I'm getting warning from GLib that myClass doesn't have the 
property.
Note: Vala compiles just fine, but when running is when I'm getting the 
error.

It would be useful to update a little the examples from 
http://live.gnome.org/Vala/Documentation, or make the properties explanation 
more clear.
Is it always needed to use backend attributes of the classes for every 
declared properties ?
How I refer to the properties inside the class, with the property name or 
the backend attribute ?
