When pasting html table copied from FF3 to ckeditor opened in IE 7 the following browser error is received:

Line: 16

Message: Unexpected call to method or property access.

Steps to reproduce:

1. Open the file 'table.html' in FF, select the table from 'For users:' to the last record in the table.
   
2. Paste the content(Ctrl + v) in ckeditor opened in IE7
   
3. Press 'Enter' immediately after it (see ckeditor1.jpg from the attached files)

The problem is that partial table contents like below is corrupted in IE, result in distorted DOM structure that's error prone, we should be looking for fixes in our own parser before sending it to browser.

var table = '<tr><td>cell</td></tr>';
element.innerHTML = table;
element.lastChild.nodeName; // "/tr"

Note that FF also give different result by ignoring all table cell elements.

I think we should mask pasting errors until #5309, which will bring DTD aware pasting.

After the patch table is pasted correctly, so masking JS error seems to enough.

Fixed with [5854].

The fix doesn't resovle the issue, reverted with [7239].

I cannot reproduce this issue anymore. Code that handles pasting was rewritten in 90% percentage since this issue was reported.
