As i have the same problem i think i can add some additional information to reproduce this issue:
Ubuntu 11.10 Unity
Thunderbird is placed on virtual desktop number 4 ( I'm mainly working on virtual desktops 1 to 3 and number 4 is for mail and so on)
Second i have some message filters which sorts mail into seperate folders.
I observe the following problems with the mail applet:
1. If i'm clicking on the mail applet indicating new mail, i expect that thunderbird will be shown (and i get switched to desktop 4).
Instead nothing happens and the new mail number resets.
2. If i'm going directly to desktop 4 and read my mail, the applet won't update the numbers.
3. If mail was sorted by my filters, i get an unread mail number in inbox and the subfolder in which the mail was sorted into.
That means that the applet says i have 1 new message in inbox and there is none because this message is in a subfolder. The applet also states that in the subfolder is a new message, which is correct.
