This seems to happen when I change workspaces using a keyboard
sequence.  It /may/ have something to do with use of the Workspace
Switcher to move windows.  Moreover, I think it is closely related to a
long-standing "alt-tab kidnapping other workspaces' windows" bug.

I can't reproduce it reliably, but it happens every few hours of heavy
use.

Other notes:  Debian testing, click-to-focus, GDM.
