wp_dropdown_categories won’t link to correct archive

Hello!

I’m using wp_dropdown_categories to show a custom list of categories in the sidebar. But since I’m using qtranslate the “submit”-button gives the wrong page and switches to default language!

how can I fix this?

Here’s the code:

<form action="<?php bloginfo('url'); ?>" method="get">
	<div>
		<?php _e('Select:'); ?><br />
		<?php /*get_query_var('cat');*/
			wp_dropdown_categories('child_of=1&orderby=name&show_count=0&hierarchical=1&hide_empty=1'); ?>
			<input type="submit" name="submit" value="&raquo;" />
	</div>
	</form>

thx for help,
