EntityMalformedException is thrown due to an unwanted call to hook_node_update in og_menu

Problem/Motivation

There is a problem when inserting/updating a node when this module runs alongside Menu Node API

In Menu Node API's _menu_node_invoke function, there's

...
module_invoke_all('menu_node_' . $hook, $link, $node);

Where $hook can contain 'update/insert/delete' resulting in a module_invoke_all('menu_node_update/insert/delete').

The problem is that Drupal thinks that the og_menu module implements those hooks whereas it only implements hook_node_update/insert/delete (that's because there is a module called og and a function called og_menu_node_update even though the code does not belong to the og module)

Since a hook_node_update/insert/delete expect a $node as its only parameter, the $link provided by menu_node's module_invoke_all('menu_node_' . $hook, $link, $node) ends up in a EntityMalformedException.

I already created a ticket in Menu Node API's issue queue for this problem (see EntityMalformedException is thrown due to an unwanted call to hook_node_update in og_menu) but I think the issue lies here and not in their module.

Proposed resolution

In the aforementioned ticket, I didn't know what was the best option to resolve this issue, but now I think you should test the parameters you receive in your hook_node_update/instert/delete implementations to avoid any issues.
