Getting rid of br class="clear", using new clearing class

Hi,

I want to get rid of the ugly

at the end of user submitted content using the new clearing class instead.

On the homepage of BerlinerStrassen.com I have this "Billige Shoutbox" (=cheap shoutbox, made with cck+views) where this problem gets on my nerves the most. You can see that the right most cell of the shoutbox table containing the user shout has that "br class clear" on the end. But you can find it for instance at the end of all blog posts, too.

My theme is a modification of Abac 5.x-1.4 and as I'm no theming expert I seem unable to find the right code spot where this br is inserted. Your help, any hints would be appreciated!
