IE8: Unspecified error when pasting with a selection in the editor

[Teresa Monahan]

To Reproduce:

1. Open any CKEditor sample in IE8.
2. Insert a table
3. Select the table by clicking on the table border or by selecting table on the elements path bar.
4. Use Ctrl+C to copy the table and then Ctrl+V to paste it.

Problem: A browser error occurs and the table is removed from the editor.

The error is an Unspecified Error in wysiwygarea/plugin.js at line 125.

This also occurs with other content e.g. paste the following into Source view, switch to wysiwyg and repeat steps 3 & 4:

<div style="width: 500px">
	Some text goes here</div>

This is reproducible since revision [6559]. It seems to be specific to IE8 as this testcase works fine in IE7 and IE9. I cannot reproduce it in 4.x builds, however this is an important issue for us so we would appreciate your input on it.

I can confirm this issue for CKE 3.x.

There are also two other issues caused by this revision: #7975, #8575.
