Workspace switcher applet does not let me drag windows to other workspaces since karmic

Binary package hint: gnome-applets

Before upgrading to karmic, I could do this in the Workspace Switcher applet in the bottom panel:
Drag a window from one workspace to another by dragging its depiction in the small workspace preview witihn the panel.

This does not work in 9.10 for me. The version of the workspace switcher applet is 2.28.0

The mouse pointer still changes to "dragging"-style when I try this, but nothing happens with the window.
