Thread:Project:Support desk/Missing Namespace Tab Labels in Vector/reply

I forgot to mention that the problem isn't just with the Page/Talk namespaces. In those namespaces the tabs are simply blank. If you go to Special:SpecialPages, the tab changes to (literally) read "& lt;vector-namespace-special& gt;". User pages show "User" in both tabs. The MediaWiki namespace shows "MediaWiki" in both tabs, and so on.

EDIT TO ADD: Apparently the problem is only in Vector, which is my site default. Switching to MonoBook fixes it. There's nothing in MW:Vector.css that affects it though (I tried blanking it out as a test, and anyway, both wikis have the same Common.css and Vector.css).

EDIT: Bump?
