--- Comment #11 from Carlos Garcia Campos <cgarcia at igalia.com> ---
Ok, I know what the problem is. The crash is in WTR, when handling contextClick. GTK and EFL use WKBundlePageCopyContextMenuItems that always returns a valid array, even if it's empty when there's not contexct menu, but other ports use WKBundlePageCopyContextMenuAtPointInWindow() that can return nullptr. The returned value is used below without any null check. I don't know why we need different code for EFL and GTK here, and I don't know why WebPage::contextMenuAtPointInWindow() can return nullptr, but WebPage::contextMenu() doesn't. But this is an exiting issue in any case so I'll open a new bug.
