I'm going to close this bug as Invalid because for bugs managed by Launchpad, it does not occur anymore. The reported instances where it does happen are for when bug comments are imported from an external Bugzilla instance, and for those cases the email subject being [Bug 1234] is by design since we only have the bug id.
