post_save_moderation breaks confirmation view

[nate-django@…]

I tried out the new moderation tools and I found that when a comment is deleted in the post_save signal handler post_save_moderation(), it breaks the comment confirmation view because the comment instance is gone and _get_pk_val() returns None. This causes the following traceback for the redirected request.

Exception Type: ValueError at /comments/posted/
Exception Value: invalid literal for int() with base 10: 'None'

Shouldn't moderation.py connect to the comment_will_be_posted signal so post_comment() can handle the signal response?
