Not sure I would call it "easy" but I was able to reproduce the problem
and then get it to work with this, at least in my testcase:
f := func(a ...string) error {
switch t :=
mv.CallSlice([]reflect.Value{reflect.ValueOf(a)})[0].Interface().(type) {
case error:
return t
default:
return nil
}
}

I was told by the testers that this patch did not work. The error message

That's easy to fix....
