[Mediawiki-l] MediaWiki:Common.js not loaded

[Samuel Lampa]

MediaWiki:Common.js doesn't get "loaded" into the generated HTML from my 
wiki (MW 1.14.0).
I've tried making a full refresh (Ctrl + Shift + R in firefox) and 
adding $wgUseSiteJs = true; to LocalSettings.php

The user js is loaded though, i.e. I see the following line in the 
generated HTML:

<script type="text/javascript" src="/w/index.php?title=User:My-username/monobook.js&amp;action=raw&amp;ctype=text/javascript"></script>

Are there some extra settings needed?
Else, the following lines of code in includes/SkinTemplate.php seem 
suspicious to me...

                if( $wgUseSiteJs ) {
                        $jsCache = $this->loggedin ? '&smaxage=0' : '';
                        $tpl->set( 'jsvarurl',
                                self::makeUrl('-',
                                        "action=raw$jsCache&gen=js&useskin=" .
                                                urlencode( $this->getSkinName() ) ) );
                } else {
                        $tpl->set('jsvarurl', false);
                }

Will they not generate something like 

 ...User:My-username/monobook.js...

rather than 

 ...MediaWiki:Common.js...

in the generated script inclusion tag? 

Kind Regards
