Updating php 5.3 to 5.4, mostly you will get problem like below
components/com_k2/models/item.php on line 596

Here are very simple solution that works for me

components\com_k2\views\itemlist\view.html.php
Line 139.
Add: $category->event = new StdClass;

components\com_k2\models\item.php
Line 595.
Add: $item->event = new StdClass;
