menu.Actions() panics

[ilius]

menu.Actions() panics for me. My code:

webBrowser.ConnectContextMenuEvent(func(event *gui.QContextMenuEvent) {
    event.Ignore()
    menu := webBrowser.CreateStandardContextMenu()
    actions := menu.Actions()
    fmt.Println("actions", actions)
    // menu.Actions() panics
    // firstAction := actions[0]
    action := widgets.NewQAction2("Query", webBrowser)
    action.ConnectTriggered(func(checked bool) {
        text := webBrowser.TextCursor().SelectedText()
        if text != "" {
            doQuery(text)
        }
    })
    menu.InsertAction(nil, action)
    menu.Popup(event.GlobalPos(), nil)
})

I want to pass menu.Actions()[0] to menu.InsertAction.

Traceback:

panic: interface conversion: interface {} is []interface {}, not []*widgets.QAction
