The same here. I can reproduce this bug by hitting alt-space or by clicking on window menu. Title bars from all windows disappear. I need to reload window manager (using Compiz Fusion Icon program) to recover from this situation.

One more - I can access window menu by right clicking the window title bar and it doesn't crash my WM. So the problem is not with the menu itself. For now I've just disabled menu item from my title bar (no accidentally clicks) by changing /apps/metacity/general/button_layout key (in gconf-editor) from
menu:minimize,maximize,close
to
:minimize,maximize,close

Status changed to 'Confirmed' because the bug affects multiple users.
