I have the same problem told by Vincenzo in the commentary above. Iḿ using Beryl in Kubuntu Edgy Eft and icon of adept notifier don't stand in the systray. If I kill the adept notifier e start it again it will be hidden, but the empty space in the systray remains. If the systray is chaged, like to add/remove another icon, the apedt notifier icon will be pushed off the systray. As Vincenzo said the bug is in adept, since all other applications don't behave like that.
