qTranslate get content by language using wp_query

Question

I've similar problem to the issue described here.

On my bilingual website here http://redscouseworld.com/ I'd like to display posts only in Polish language.

And here http://redscouseworld.com/en/ I want to show posts written in English only.

I added following code to my homepage:

<ul>
<?php $the_query = new WP_Query( 'showposts=10' ); ?>
<?php while ($the_query -> have_posts()) : $the_query -> the_post(); ?>
<li><a href="<?php the_permalink() ?>"><?php the_title(); ?></a></li>
<li><?php the_excerpt(__('(more…)')); ?></li>
<?php endwhile;?>
</ul>

And you can see that on English version both post types are being displayed (Polish and English) - half of them as untranslated ones. How can I display only proper ones on each site?

I tried to hide them using qTranslate function "Hide untranslated content" but the result was empty page.

I'd be grateful for your help! Thanks in advance!
