Spaces in usernames breaking the site

hey guys i see the notice on the registration form that spaces in usernames arent allowd yet i just made an account with a space in the username and it broke straight away, cant view lots of various URLS, they break, i found an old post from 2005 saying ... this will be fixed in the next release, yet 9 years later this is still broken?

What version of Joomla?
What version of CB?

Please when posting on a Potential bug forum you need to provide basic information like this and exact method to replicate on a clean latest CB version installation.
