Miscounts number of messages in the inbox

I am, here, working on the assumption that the 'Inbox: Xm' thing in the dropdown from the envelope in the indicator bar is a count of the number of new messages in what Reddit calls the 'letterbox' (perhaps that's another bug :) )

Even if I have some unread mail in my letterbox (such that the envelope on the Reddit website is red), the count of messages in the above dropdown remains at zero. I've attached a screenshot showing both.

I've another bug open about this package (1059882), which I think is the miscolouring of the envelope, wheras this bug refers to the counting of the messages. I'm well aware that the cause may be the same, but the effect isn't :)

In traditional step-by-step form:

What I see:
1) Have unread messages in your reddit inbox
2) Click on the envelope in the notification area
3) See the message count be zero

What I expect:
1) Have unread messages in your reddit inbox
2) Click on the envelope in the notification area
3) See the message count reflect the number of unread messages.
