New mail notifications pop up in a window instead of in a desktop notification

[igi]

Binary package hint: mail-notification

In Ubuntu Maverick, new mail notifications pop up in a window in the centre of the screen instead of appearing as desktop panel notifications (libnotify).
This is not happening everytime I get new mails, but always when I have new mails in my gmail account. If I get mails only in my other three accounts, notifications are properly displayed in the notification area.

I use Mail Notification 5.4 with Google apps [using the gmail way to login]. I always get my mails in pops up instead of notification area which annoys. If i switch off the notification i miss the emails. I confirm on the above bug.
