Create a new menu item and select Web Links - List All Web Link Categories with default options, Save & Close.
Go to the front end and select the new link from the menu.

Actual result
The list shows the category Uncategorised after the PHP warning:
Warning: count(): Parameter must be an array or an object that implements Countable in C:\www\joomla380\components\com_weblinks\models\categories.php on line 95
System information (as much as possible)

Fixed by inserting the following lines before line 95 in components/com_weblinks/models/categories.php
if (!is_array($this->_items)) { $this->_items = array(); }

This issue was fixed in latest codebase, so I'm closing.
The issue is caused by a defective query.
Change the lines 153 - 154 by
$query->select('CASE WHEN a.created_by_alias != "" THEN a.created_by_alias ELSE ua.name END AS author')
->select('ua.email', 'author_email')
And the $item is not empty.
