Subject: [PATCH] Fix exception thrown in mw.util.addPortletLink * As of jQuery
 1.4.4, Sizzle's query must be a string (it does a query.replace call before
 everything else). It fails otherwise. * In REL1_17 and 1.17wmf1 this isn't a
 problem since jQuery 1.4.2 is there, in which Sizzle didn't fail on
 non-strings yet. * Nonetheless this is undocumented support, we should make
 sure that the variable passed is a string on our side * Adding a check for it
 in mw.util.addPortletLink's nextnode argument. * Adding a test to
 mw.util.test that calls addPortletLink with three arguments, making nextnode
 implied undefined/null. This test returned "ERROR" before I made the fix in
 mw.util.addPortletLink.

Exact error: TypeError: Result of expression 'query' [undefined] is not an object.
Origin: line 4085 of jQuery/mediaWiki module load.
Line 4081: Sizzle = function( query, context, extra, seed ) {
Line 4085:  	  query = query.replace(/\=\s*([^'"\]]*)\s*\]/g, "='$1']");
