Problem with removing advanced tab in link and image dialogs

[Damian]

Insert the following code after CKEDITOR.replace( 'editor1' ); in ckeditor/_samples/replacebycode.html

CKEDITOR.on('dialogDefinition', function( ev )
{

	var dialogName = ev.data.name;  
	var dialogDefinition = ev.data.definition;
   
	switch (dialogName) {  
	case 'image': //Image Properties dialog      
		dialogDefinition.removeContents('advanced');
		break;      
	case 'link': //image Properties dialog          
		dialogDefinition.removeContents('advanced');   
		break;
	}
});

This should remove the advanced tab from the image and link dialogs.
Save the html page and view it in a web browser.
Click on the 'Insert Link' toolbar icon.
The advanced tab is removed.
Click cancel - the dialog closes correctly.
Open the dialog again.
Enter a link and click ok.
The dialog closes and the link is inserted correctly into the editor.
Now click on the 'Insert Image' toolbar icon.
The advanced tab is removed.
Click cancel - the dialog does not close and an error is shown in the console.
Entering an image url and clicking ok does not close the dialog either.
The only way to recover is to close the browser tab / window.

Error in Firebug:

this._.contents[pageId] is undefined
[Break on this error] return this._.contents[pageId][elementId];\r\n

I'm not sure if there is even another ticket filed with related problems, anyway, we will find it later in future reviews of pending tickets.
