[Gtk-sharp-list] EventHandler error

[Moritz Balz]

Hi,
I've written a little Gtk# app containing this line:

    win.DeleteEvent += new EventHandler (CallbackWindowClose);

This worked fine for weeks, but after installing the latest Mono (0.14)
and Gtk# snapshots (from CVS) today I get the following compiler error
message:

    Test.cs(35) error CS0019: Operator + cannot be applied to operands
    of type `GtkSharp.DeleteEventHandler' and `System.EventHandler'

Can someone give me a hint on what's wrong?

Thanks
Moritz
