I am developing a multilingual website with qtranslate.
In the breadcrumbs above the albums I noticed, that the toplevelpage (with the root switched off) was listed with all (in my case 4) languages side by side.
The solution was to change line 175 in wppa-functions.php from
$wppa['out'] .= wppa_nltab().'<a href="'.get_page_link($parent).'" class="wppa-nav-text b32" style="'.__wcs('wppa-nav-text').'" >'.$title.'</a>';
into
$wppa['out'] .= wppa_nltab().'<a href="'.get_page_link($parent).'" class="wppa-nav-text b32" style="'.__wcs('wppa-nav-text').'" >'.__($title).'</a>';
