race condition in CSS validator?

There is some sort of race condition in the CSS validator.  It may be
related with bug 8867 (http://www.w3.org/Bugs/Public/show_bug.cgi?id=8867).
The next code may either return no warnings, one warning, or two warnings
when validated with no special profile, for any medium, and with all
warnings enabled:

body { color: #606060; background-color: #ffffff }

..top-navbar, .navbar { color: #909090; background-color: #ffffff }
..top-navbar, .navbar { font: 90% Arial, sans-serif }
..top-navbar          { text-align: right }
