Deletion of multiple comments script-error

[Ezd]

If you add two comments to a status update, then delete the first commment and second comment. For what I can see there's a script error in IE8 when deleting the last comment.

After the script error, if you try to click the Reply button the multiline textfield won't come up.

This is only tested in IE8. Not sure about the other browsers but it should be checked.

Script error from IE8:
