mkdir Permission denied in wp-csv.php on line 323 (resolved)

Hi

I propose to fix the warning/error

PHP Warning: mkdir() [function.mkdir]: Permission denied in …/wp-content/plugins/wp-csv/wp-csv.php on line 323

due to unsuccessful mkdir.
solution is to check if parent folder is writable
file wp-csv around line 323
before :

public function get_csv_folder( ) {
                        $chosen_folder = '';
                        $paths = $this->get_paths( 'wpcsv_backups' );
                        foreach( $paths as $p ) {
                                if ( ( !file_exists( $p ) && ( mkdir( $p, 0755 ) ) || $this->folder_writable( $p ) ) ) {
                                        $chosen_folder = $p;
                                        break;
                                }
                        }

after :

public function get_csv_folder( ) {
                        $chosen_folder = '';
                        $paths = $this->get_paths( 'wpcsv_backups' );
                        foreach( $paths as $p ) {
                                if ( ( !file_exists( $p ) && ($this->folder_writable(dirname($p))) && ( mkdir( $p, 0755 ) ) || $this->folder_writable( $p ) ) ) {
                                        $chosen_folder = $p;
                                        break;
                                }
                        }

(should I open a ‘trac’ ?)
