glib.IdleAdd crashed with panic: reflect: Call using reflect.Value as type string #417

please provide minimal code to reproduce.

I just figured out. If I define a function like:

func (btn* MyButton) SetLabel(label string) { ... } Then call it as: glib.IdleAdd(btn.SetLabel, "new label")

It will crash.

Then I changed the function to: func (btn* MyButton) SetLabel(data reflect.Value) { str := data.String() ... }

Then it works.
