When node type name is different from module name...

I have the may 2006 version installed and I noticed that 'my workspace' for nodes such as og wasn't showing the edit/delete links. On debugging the code, I found this critical error.

from workspace_list()
//Check the nodetype's access hook.
$function = $row->type. '_access';

The problem with the above code is we are assuming the module name is the same as the node type. Valid example - blog - blog_access.

But this will break where the module name is not equal to the node type name. Example 'storylink' - 'vote_storylink_access' or even OG and 'groups'.

A simple fix will be :
//Check the nodetype's access hook.
$function = node_get_base($row->type). '_access';

This will get the actual module name.

Any reason why the former approach was chosen? I'm not a php guy, so I might be missing something very basic here.

Anyway, this seems to work fine, but I was wondering if I'm overlooking anything.
