If the name of a navigation link is blank in Special:Allmessages, the Classic and Cologne Blue skins will try to print it anyway, unlike the other skins. So, with a default installation you will see a "-" in the quickbar links where "Site Support" was intended to be. This bug is simple to reproduce: Create an account on test.wikipedia.org, and set your preferred skin to either of those two skins, and you will see a blank link in the quickbar links. Same result in my installation, unless you remove "Site Support" from $wgNavigationLinks, or define "sitesupport" in Allmessages.
Created attachment 172 [details] fixes the bug for the classic skin Have only tested it on b2, but I see that the file hasn't changed in b3
