Bug#497529: Icon in Panel is only partial visible

[Armin Fuerst <armin.fuerst@beko.at>]

Package: hplip
Version: 2.8.6-2

Most of the time during login, the hp-systray icon is only partially
visible in the panel. Before, it appears on the top-left corner of the
desktop (below the panel) for a short period of time.
If I manually restart it, it is completely visible.
I've attached 2 images showing the results in the panel:
hp-systray.bad.png shows the partially visible icon and
hp-systray.good.png shows the icon after manual restart.
