TYPO3 Core

Hi,

With TYPO3 4.7.4 the RTE doesn't load in IE 7,8,9 in "Frontend Edit".

Steps to reproduce

- download IntrodutionPackage 4.7.4 and install
- in ExtManager install feedit
- set config.admPanel = 1 in MainTemplate at root
- open in a site and activate in AdminPanel "Display edit panels" and "Display edit icons"
- edit an text Element with IE

IE9 is only showing the loading screen of RTE but no Information of an error, use IE8 to get a Error Message: "Object expected at line 865"

This is in htdocs/intro474/typo3/sysext/rtehtmlarea/htmlareahtmlarea.js the function

appendToLog: function (editorId, objectName, functionName, text, type) {
        var str = 'RTE[' + editorId + '][' + objectName + '::' + functionName + ']: ' + text;
        if (typeof(type) === 'undefined') {
            var type = 'info';
        }
        if (typeof(console) !== 'undefined' && typeof(console) === 'object') {
                // If console is TYPO3.Backend.DebugConsole, write only error messages
            if (Ext.isFunction(console.addTab)) {
                if (type === 'error') {
                    console[type](str);
                }
            } else {
-----> this is line 865        console[type](str);
            }
        }
    }
