I have located the problem method:

github.com

magento/magento2/blob/7e9d181/app/code/Magento/CatalogImportExport/Model/Export/Product.php#L404-L423


protected function initCategories()
{
    $collection = $this->_categoryColFactory->create()->addNameToResult();
    /* @var $collection \Magento\Catalog\Model\ResourceModel\Category\Collection */
    foreach ($collection as $category) {
        $structure = preg_split('#/+#', $category->getPath());
        $pathSize = count($structure);
        if ($pathSize > 1) {
            $path = [];
            for ($i = 1; $i < $pathSize; $i++) {
                $path[] = $collection->getItemById($structure[$i])->getName();
            }
            $this->_rootCategories[$category->getId()] = array_shift($path);
            if ($pathSize > 2) {
                $this->_categories[$category->getId()] = implode('/', $path);
            }
        }
    }
    return $this;
}

Definitely this failure is a bug, because even if your data is not correct then Magento 2 should show an end-user message instead of an automatic PHP low-level message.
