Object doesn't support property or method 'packet'

[sjbog]

Got this error on chrome and IE (haven't test others):

Uncaught TypeError: Object [object DOMWindow] has no method 'packet'
SocketNamespace.emit 

socket.io.js:2098

IE:

SCRIPT438: Object doesn't support property or method 'packet' 
socket.io.js, line 2098 character 5

since yesterday, when updated to 0.7.11
same with 0.8.0

On server's console don't see any errors

Which version of IE? Which transports are you using? What does your client code look like?

Tried websockets and xhr-pooling:
Client side:

socket.on('connect', function connected() {
    console.log('Connected to remote host');
    setLinkState(1);
    toggleControlButtons();
    statsIntervalHandle = setInterval(socket.emit, 3000, "get_stats", {"value": "all"});
});

socket.on('stats', function() {
    var outputArr = Array.prototype.slice.call(arguments), len = outputArr.length;
    while(len--) {
        console.log('got stats', outputArr[len]);
        setStats(outputArr[len]);
    }
});

Server side:

socket.on("get_stats", function(data) {
        switch(data['value']) {
            case 'memory_usage':
                    socket.emit("stats", getMemoryUsage(true));
                break;
            case 'all':
            default:
                    socket.emit("stats", getMemoryUsage(true), {
                        "mysql_rows": DBrows.length,
                        "rules_in_memory": rules.length,
                        "stocks_in_memory": stockNames.length,
                        "open_prices": Object.keys(startPrices).length,
                        "current_prices": Object.keys(currentPrices).length
                    });
        }
    });

Looks like the issue is in setInterval (setTimeout will do the same) of my code:
when it invokes "socket.emit" context is window

Code executed by setTimeout() is run in a separate execution context to the function from which it was called. As a consequence, the this keyword for the called function will be set to the window (or global) object, it will not be the same as the this value for the function that called setTimeout.

When you pass a method to setInterval() (or any other function, for that matter), it will be invoked with a wrong this value.
