Js error when removing plugins from FULL version CKEditor

[GLK]

Steps to reproduce

1. Standard includes to start everything off just fine.
2. Trying to remove some plugins for a simpler look.

   $(function() {
     var ckinstance = CKEDITOR.instances['message'];
   
     delete CKEDITOR.ckinstance;
     CKEDITOR.replace( 'message',  {
         customConfig: '/js/ckeditor_email_config.js'
     });
   });   
   

3. Followed with the email_config.js

   CKEDITOR.editorConfig = function( config ) {
   	// Define changes to default configuration here. For example:
   	  
     config.removePlugins = 'image,language,gg,flash,base64image,pastbase64'; 
     
     config.scayt_autoStartup = true;
   };
   

Expected result

FULL toolbar minus some things I don't want users to see... This list is subtantially longer in reality, but error occurs with just these!

Actual result

TypeError: a is undefined

...CKEDITOR.env.isCompatible)return null;a=CKEDITOR.dom.element.get(a);if(a.getEdit...

ckeditor.js (line 322, col 76)

1. I can see that you are using many custom plugins.
2. You must know that some plugins depend on each other. If you have an image plugin, on which other plugins depend, and you remove this plugin but not others - error will be thrown.

I have removed the language, flash and image plugin from default full package (they were created by CKSource) - but no error has been thrown. Because of that I can't see any problem in editor and will close this issue as invalid.

NOTE: Please check IE dev-tools console and see what error message is reported there. My guess is that you have some custom plugin that depends on image plugin. Your solutions are removing that custom plugin as well or bring back image plugin.

@glkaup please investigates this issue on your own. If you find the culprit and you still think this is editor fault, please comment. I will consider reopening this ticket.
