When I comment on a bug that I'm already subscribed to, I see this:
[ ] E-mail me about changes to this bug report
If I'm already getting emailed about changes to this bug report, this checkbox should be checked already.
In this case, unchecking the checkbox would unsubscribe me from this bug.
An alternative fix is to not display the checkbox and text when I'm already subscribed.
