Captions &?Descriptions in gallery

Hi, I would like to have multilangual descriptions and captions in gallery. It doesn’t work with [:fi] something finnish [:en] something english. I had to replace some code in media.php:

if ( $captiontag && trim($attachment->post_excerpt) ) {
			$output .= "
				<{$captiontag} class='wp-caption-text gallery-caption'>
				" . wptexturize(__($attachment->post_excerpt)) . "
				</{$captiontag}>";
		}

for

if ( $captiontag && trim($attachment->post_excerpt) ) {
			$output .= "
				<{$captiontag} class='wp-caption-text gallery-caption'>
				" . qtrans_useCurrentLanguageIfNotFoundUseDefaultLanguage($attachment->post_excerpt) . "
				</{$captiontag}>";
		}

as I read in a forum.

Is there some sustainable way of being able to translate the image information?
