Check if the_content is empty?

Hi,

I’am trying to use this code inside the loop on category.php

<?php
if( empty($post->post_content) ) {
    // Do stuff with empty posts.
} else {
    // Do stuff with posts with content.
    the_content();
}
?>

But “// Do stuff with empty posts” runs even if the_content is not empty. What am i doing wrong?
