dibi na linuxe (webhostingu)

Ahojte.

Neviem čim to je ale na linuxe mi dibi nechce spravne fungovať. Majme napr. tento kod:

<?php
include('./dibi.compact.php');

dibi::connect(array(
    'driver'    => 'mysql',
    'host'      => 'localhost',
    'user'      => 'user',
    'pass'      => '',
    'database'  => 'db',
    'charset'   => 'utf8',
    'profiler'  => true
));

    $result = dibi::query('SELECT [url],[title],[big_btns] FROM [nodes] WHERE [main_page] = 1 AND [nav] = 1 ORDER BY [order] ASC');

    dump($result);

    $assoc = $result->fetchAssoc('url,=');

    dump($assoc);

?>

kde dump() je moja obdoba funkcie print_r.

dump($result) – vypise to rovnako aj na windowse aj na linuxe:

DibiResult Object
(
    [driver:private] => DibiMySqlDriver Object
        (
            [connection:private] => Resource id #3
            [resultSet:private] => Resource id #4
            [buffered:private] => 1
        )

    [xlat:private] =>
    [meta:private] =>
    [fetched:private] =>
    [withTables:private] =>
    [class:private] => DibiRow
)

ale dump($assoc) už na linuxe vypiše len prázdne pole, a na windowse pole napr tvaru:

Array
(
    [fotogaleria] => Array
        (
            [url] => fotogaleria
            [title] => Fotogaléria
            [big_btns] => 1
        )

    [o-nas] => Array
        (
            [url] => o-nas
            [title] => O nás
            [big_btns] => 1
        )

    [archiv] => Array
        (
            [url] => archiv
            [title] => Archív
            [big_btns] => 0
        )

Ako to je možné?
