rethinkable on "Problem with "excerpt_more" link"

Please help!

On the site wich I develop, on the page (and some other)
http://www.legeartis.rs/category/pravno-ekonomske-oblasti/kompanijsko-pravo/
problem can be seen.

I modified post excerpt that instead standard "[...]" at the end, now there is "...više >>" (more) with link to the full post page.

But, as a add that - post list was broke up, as you saw on first link.

I put this code

function new_excerpt_more($more) {
       global $post;
	return '<a href="'. get_permalink($post->ID) . '"> ...више » </a>';
}
add_filter('excerpt_more', 'new_excerpt_more');

in file functions.php

NOTE: If I put instead

'. get_permalink($post->ID) . '

some simple web adress, there is no problem. For example:
href="http://www.legeartis.rs"
Every post get nice link to that web page "...više >>" and everything cool.

Well, it's look that creating a links make problem. Also, some posts now dont have that link at all ( but evrey post have [...] at the end, without this change). On post where making link was unsuccessful next post look like "child" of that bad one before.

Can someone tell me how to solve this problem.

Sorry for my english.
