Only happening in WebKit nightly r54122 - Firefox etc unaffected.

Console message is:

TypeError: Result of expression 'i' [undefined] is not a valid argument for 'in'.

static.ak.fbcdn.net/rsrc.php/z4RT5/hash/e5pvn624.js:31



The offending code appears to be (whitespace added):

var a=function(g,k) {
var h='on'+k,i=DataStore.get(g,b);
if(k in i) {
 if(g[h]!==d) throw new Error("`"+h+"' listen handler gone!");
 return;
}
i[k]={};
var j=g[h];
g[h]=d;
if(j)Event.listen(g,k,j,Event.Priority.TRADITIONAL);
}

Implying an unexpected results from the DataStore object.
