1) The file select-arrow.gif is missing from async/images
Edit: As for this issue this is likely introduced by some module which points there and not necessarily a theme matter.

2) If you had a logo to the header the secondary menu shifts to the left/center and overlaps it.
Something I fixed by replacing in page.tpl.php the following:

<?php if ($logo): ?>
        <a href="<?php print $front_page; ?>" title="<?php print t('Home'); ?>" id="logo" class="grid_2 alpha">

with:

    <?php if ($logo): ?>
        <a href="<?php print $front_page; ?>" title="<?php print t('Home'); ?>" id="logo" class="grid_14">
