WPMU dashboard mucks up WP sidebar nav

Hi,

Just installed WPMU on my first WP site and it makes a mess of the sidebar in the WP admin - seems to center align all text..

I'd suggest the problem is here:

li [class^="icon-"], li [class*="icon-"] {
display: inline-block;
width: 1.25em;
text-align: center;
}

Cheers
