Have the same issue when I create just a basic project.
The application have just a button to open a popup which only contain 
mathmlEditor.
When I open the popup, it crash.
The popup only contain :

<?xml version="1.0" encoding="utf-8"?>
<mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" 
width="400" height="300" xmlns:fmath="http://www.fmath.info" 
creationComplete="init();">
<mx:Script>
        <![CDATA[

            protected function initEditor():void
            {
                editorId.setConfiguration("defaultFont", "fraktur");
                editorId.setConfiguration("defaultFontSize", "40");
                editorId.setConfiguration("defaultBold", "true");
                editorId.setConfiguration("defaultItalic", "true");
                editorId.setConfiguration("defaultForegroundColor", "red");
                //editorId.disableToolbar("toolbar_top1", "true");
                //editorId.disableButton("toolbar_Equation1", "true");              
            }

            protected function saveImageToServer(event:MouseEvent):void
            {
                editorId.saveImageOnServer(null);
            }

        ]]>
    </mx:Script>
        <fmath:MathMLEditor id="editorId" editorWidth="800" editorHeight="500"  initialize="initEditor()">
            <fmath:mathML><![CDATA[<mrow><mtext>abc</mtext></mrow>]]></fmath:mathML>    
        </fmath:MathMLEditor>
</mx:Panel>

I juste do a PopUpManager.addPopUp.
Thank's
Tuan
