In SpecialVersion.php the global variable $wgSkinExtensionFunction is used. But in DefaultSettings.php and Setup.php the variable is named $wgSkinExtensionFunctions, with an s at the end. Bacause of this skin extension functions are not listed at Special:Version.
Created attachment 4619 [details]
Updated three instances of $wgSkinExtensionFunctions
I found three instances (out of four) in SpecialVersion.php where there was no "s" on the variable name.
Fixed with r30605.
