Indent when title is long

I am trying to help a friend out with her WP-site.
I have upgraded it from a long since outdated version of WP to 3.5.1
and that worked fine. There is a problem though: there’s an indent in the title if the title is too long. I′m sure it has something to do with the CSS but I dont know where to start. The theme is called Artemisia.

The HTML for the div container is:

<div id="head" class="clearfloat">

<div class="clearfloat">
	<div id="logo" class="left">
	<a href="<?php echo get_option('home'); ?>/"><img src="<?php echo get_option('home'); ?>/wp-content/themes/arthemia/images/title.png" width="177px" height="39px" alt="" /></a>
	<div id="tagline"><?php bloginfo('description'); ?></div>
	</div>

        <div id="menu" class="left">
<h2 class="title"><?php the_title(); ?></h2>
</div>

#menu {
    border:0;
	background-color: #fff;
	margin-left: 45px;
	font-family: "Courier New", Courier, mono;
	margin-top: -30px;
}
.left, .alignleft {
	float:left;
	}

Any ideas where to start looking?
