Pulling a Window from another workspace does not work

[Holker]

If for example I am in workspace 2 and my name is called in Chatzilla (active in workspace 1), a minimised bar appears and lights up in workspace 2 as a warning.
In workspace 2 I right-click the minimised bar and try to pull the Chatzilla windows from Workspace 1 to Workspace 2 by selecting "Move to Another Workspace" and then clicking on "Workpace 2". But nothing happens, even this option seems to available. Aparantly you can only send windows away to other workspaces, but you cannot pull them back. You are forced to change workspace then...
