Comment 11 for bug 726101

Reproducable when force quit an application, e.g. totem (in a loop), gedit by loading a 75MB file (window not responding).
After force quit unity crashes and window decorations are gone.
Open windows are moved from previous workspace, e.g. on top, to bottom row of workspace. (There're currently nine workspaces.)
