[Plugin: WordPress.com Stats] WP Stats Clicks breaks some links

I’m using WP Stats 1.6.2 in WP 2.9.2 (http://www.potentialgames.com/blog).

On the Site Stats page, reported “Clicks” can break a URL. The URL is correctly formed in the blog post (and links correctly from the blog article).

Here is the specific example I found. From my article:

http://www.potentialgames.com/blog/2008/06/20/java-locking-assertion-failure/

I link to:

https://bugs.launchpad.net/xorg-server/+bug/185311/

WP Stats replaces the “+” with a space character, which breaks the URL.

Also, it would be really nice if WP Stats told me in which post the link is included.
