compiz crashes with seg fault after turning on and then off a feature in compiz-settings

[Christopher Barrington-Leigh]

I run ubuntu-classic.
After running compiz-settings program and turning on the cube, my interface is broken: compiz crashes and leaves me without any window manager. If I relaunch it, it dies with a segfault. I've turned the cube off and gone back to a wall, but compiz still crashes.

I should say that various keybindings are also broken/changed: now Ctrl-f fails to do what it should (typically move cursor forward, for example) in various applications.
And, just to make things annoying, launching metacity --replace rather than compiz --replace sort of works except that metacity still doesn't draw properly. E.g. when you move a window from one desk to another (ctrl-shift-rightarrow), the window is not drawn: it disappears. in general, drawing is unreliable.

Deleting or moving .gconf/apps/compiz* seems maybe to fix the corruption.
