Clicking the minus sign next to my name on a bug page appears not to unsubscribe me

[Matthew Revell]

Steps to reproduce:

1. Visit a bug page, such as bug 674422, and click "Subscribe".
2. Click the minus sign next to your name to unsubscribe.
3. Now click "Subscribe" again and you'll see that you're presented with the options that you'd expect if you were subscribed. Select the "unsubscribe" option and then click the green tick.
4. Your name re-appears in the list of subscribers but so does the "Subscribe option". Click "Subscribe" and you're given the options as though you're a subscriber again, so clearly you've never been unsubscribed.

The only way around this appears to be to refresh the page before trying to unsubscribe.

Anyone tackling this should check with Danilo, who is working in this part of the code base right now.

Why was this Critical? Downgrading to High.

I f this is a regression, then add the tag regression and raise it to Critical again.

This seems to happen because when you subscribe, your user link in the subscribers list indicates that you are a dupe subscriber (which you are not). Later, unsubscribing actions tries to call unsubscribeFromDupes which succeeds, but does nothing.
