Wt

In case we have a main WMenu with setInternalPathEnabled(), and submenus added to that main menu via WMenu::addMenu(), each also with setInternalPathEnabled(), we encounter a segfault.
This occurs when navigating to the item immediately upon loading the menu, i.e. when the current internal path matches the one being defined by the stack of WMenus.

Here, we then assume that the path would lead to a WMenu that has some content, and load the content. However, in case of a submenu, no content is defined, yet expected.
A case ought to catch that no content is set on the item.
