Facebook Connect IE7 Error

I have been geting an error in IE7. Disabled fb_connect module and the error was gone.
Here is the function the error is reported:

function __flash__addCallback(instance, name) {
instance[name] = function () {
return eval(instance.CallFunction("" + __flash__argumentsToXML(arguments,0) + ""));
}
}

the line highlighted :
return eval(instance.CallFunction("" + __flash__argumentsToXML(arguments,0) + ""));

IE7 sucks at error reporting, I searched for this code with no luck.

I googled this and found:

For now, I disabled fb_connect module so this error is not thrown in IE7.
