Date module attempts to create a local task for a invalid node

If a path like node/152368 is supplied with the date module enabled and the node is not a valid node id, an error occurs saying an i"nvalid argument supplied for foreach() in date.module on line 41"

The corrections lies in the date_menu function and starts on line 25

$node = node_load(arg(1))
if( $node && date_repeat_type($node->type) )

the change is adding the $node && which checks to see if a valid node object was loaded, because the node will return false if an invalid id was passwed
