[James Cunningham]

Steps to reproduce the defect:

1. Open the Ajax sample in IE8.

2. Paste the following code into source mode:

<p dir="rtl">
	paragraph 1</p>
<p dir="rtl">
	paragraph 2</p>

3. Click on paragraph 1 & press the increase indent button in the toolbar.

4. Click once on paragraph 2 (so that the frame is showing around the paragraph) & click the undo button in the toolbar.

Result: The following webpage error is displayed:

Message: Unspecified error.

Actually a dup of #7002.

This issue is still reproducible in IE8 in latest CKEditor 3.6.2.

Message: Unspecified error.
Line: 576

Got to quick with reopening this ticket. I have checked #7002 and they have the same source (the same error is thrown) thus closing this one again as duplicate of #7002.
