"New mail count" seems to be actually a "total unread mail" count instead for aggregated new mail notifications. (with 1.9.8-pre3)
I had like 10 new mails in one account after starting Thunderbird, so I got a aggregated info message instead 10 single ones. But it showed me 98 mails (I can't tell anymore if it said new or unread mails though...) instead which is the number of unread mails in all of my accounts.
