CefMenuModel::InsertItemAt fails if no items ?

[ndesktop]

I have a custom menu model which removes all items (such as Inspect, Save link etc.) for an item with type CM_TYPEFLAG_LINK.
Calling

Code: Select all

if(model->InsertItemAt(0, kIDOpenLinkInNewTab, L"Open link in new tab")) {
  LOG(INFO) << "InsertItemAt succeeded";
  model->InsertSeparatorAt(1);
}

fails for some reason (debugging into cpptoc/ctocpp does not show much).

But calling

Code: Select all

if(model->AddItem(kIDOpenLinkInNewTab, L"Open link in new tab")) {
  model->InsertSeparatorAt(1);
}

succeeds.

I suspect I'm either using InsertItemAt incorrectly, or I hit some obscure bug in menu_model_impl.cc.
Did someone else experienced this?
