User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1 (.NET CLR 3.5.30729)

when using a filter via quick search, the unread-counter in the grouped by sort header displays a negative unread counter.

Reproducible: Always

Steps to Reproduce:
1. active grouped by sort via menu: 
1a View | Sort by | Date
1b View | Sort by | Descending
1c View | Sort by | Grouped By Sort
2. use the quick search box to filter for a string - e.g. "zarg"
3. in my example, i now see a collapsed "Last Week (2/2)" Group with two unread emails of 2 total found emails
4. double click the group, it opens the two messages in new tabs
5. switch back to the "Inbox - ..." tab
6. i can now see a "Last Week (-1/2)" Group
7. switch back to the last message (rightmost tab)
8. close both messages using [x] in the right, upper corner of the tab *without* switching back to the "Inbox - ..." tab
9. i can now see a "Last Week (-3/2)" Group
10. expanding the "Last Week (-3/2)" Group, i can see two unread messages
11. clicking the "green dot" to mark the messages as unread, the unread-counter in the "Last Week (-3/2)" group increases to -1: "Last Week (-1/2)"
Actual Results:  
incorrect, negative unread counters

Expected Results:  
correct unread counters that can actually never be negative

Confirming on TB 8.

Testcase with filter resulting in 6 unread messages in group out of 7 shown.
In step 6 I do not get a negative number, but instead an overflowed interger, like 4294967295/7. I am on linux, 32bit.
The count does not change in step 9. However, when marking the 1 read message as unread, the number disappears (as if incremented up to 0) and is shown as (7) instead of (7/7).
