Insert HTML space bug IE

[Stephan]

if you insert spaces in the overrided insertHTML text mode, it gives a error. This happens in Internet Explorer 7

code:

CKEDITOR.instances["yourInstance"].insertHtml(" ", 'text');

ERROR:

  'isBlock' is null or isn't a object  ckeditor.js, Line 287 Character 56

This is reproducible on every browser. Caret has to be placed next to end of inline element. E.g foo<strong>bar</strong>^bom.

I can confirm this can be reproduced in all browsers from CKEditor 4.0 beta. To reproduce you have to put cursor behind bolded text and elements path has to show e.g. body p strong (I'm saying this because this isn't always the case in FF - browser "cool" feature with leaving element boundaries).
