9.10 Notification Area Problem

[Elite Override]

Yesterday I upgraded from 9.04 to Karmic, and everything runs smoothly except for one thing:

In my notification area there's an empty spot at the far right without an icon, I have tried moving the notification area, but the empty spot stays there, preventing further movement to the right.

Right clicking there and saying "Remove from panel" removes the entire notification area. I have removed and added it at an attempt to "restart" the area, to no avail.

Any help would be appreciated.

EDIT: Have just restarted, seems to be fixed. Was probably a bug in some application.
