SysTray widget bug when dragged out of TaskMan container

Hi, has anyone tried to drag the System Tray widget outside the Task Manager widget/container?

I have 6-7 icons in there, like compiz-fusion, kmix, inotify, klipper, regional setting (language switch), emesene (IM app) and yast updater.

When I drag the systray widget outside, or if I try to add one directly on the desktop, I only see the inotify and kmix icons, the other icons are there, I can click on them, but they are invisible or you see a very translucent yellow/green square (I use desktop translucency from compiz).

Might be a KDE bug, not opensuse, but can anyone reproduce this? If successful, I will log the bug under kde.org.
