Widget image2 : Cannot set property 'previous' of null

[Franck Valentin]

In some cases the widget 'image2' throws the error "Uncaught TypeError: Cannot set property 'previous' of null".

To reproduce it: In the source mode add (code generated from the widget):

<div style="text-align:center">
<div style="text-align:center"><img alt="" height="48" src="http://upload.wikimedia.org/wikipedia/commons/thumb/5/5f/Image-x-generic.svg/48px-Image-x-generic.svg.png" width="48" /></div>
</div>

When switching to the wysiwyg mode the error is thrown and no commands are available anymore. It seems that the problem only occurs when the option 'center' is selected.

Issue seems to come from line

if ( isCenterWrapper( el ) ) {

if ( name == 'div' ) {

var figure = el.getFirst( 'figure' ); el.replaceWith( figure ); el = figure;

}

This issue seems to be fixed with latest image2 plugin. ​https://github.com/ckeditor/ckeditor-dev/blob/master/plugins/image2/plugin.js
