cannot use func literal in listview

[ghost]

Today i've test go-gtk and i see that this error appear in listview.go file.

[iplavvia@localhost listview]$ go run listview.go ./listview.go:27: cannot use func literal (type func(interface {}, interface {})) as type func(unsafe.Pointer, interface {}) in argument to gtk.StockListIDs().ForEach [iplexsia@localhost listview]$

[mattn]

Use first argument as unsafe.Pointer not interface{}
