Under 0.11.2, when I select all subscribed groups and right click, choose
Empty, _not_ resetting New Message Counter, the groups do not empty until I
click on them individually.

In other words, after I choose Empty, it seems to do it.  But the Total
message count doesn't go to 0.  Then, if I click on the group, it resets to
0.  Alternately, if I download new messages, when the group gets new
messages the total resets properly (but if there are no new messages in the
group, it keeps the old, incorrect total).

This is new under 0.11.2, worked fine on previous beta releases.
