Undefined indexes

Some undefined index notices on my test site (with debug on) which are easy to fix:

On line 373

} elseif( isset( $_GET[ 'action' ] ) && $_GET[ 'action' ] == 'delete' ) {

and another on line 462

$url = "{$protocol}{$details[ 'domain' ]}" . ( isset($details[ 'path' ]) ? "{$details[ 'path' ]}" : "" );
