How did you get this crash? Is it fixed with the latest updates?

Hi,

I pretty much get it every time I try change a compiz setting (using
advanced compiz settings manager). Haven't tried in the last few days...
to scared to mess up my system. Will be trying again over the weekend.

setting to incomplete as we wait for Tony to test if its reproduce able for him.

[Tony Themelis (tony-athemelis)]

downloaded today's Natty build and tested.
- Any configuration change that touches the Ubuntu Unity Plugin causes unity to crash. Seems like the dependencies are not fully worked out yet, nor are settings that will not work disallowed.
- Other configuration settings work fine, e.g. "Wobbly Windows" on its own, without touching Unity Plugin.
- Still cannot change from Desktop Wall to Desktop Cube as this requires a disabling of Unity Plugin -> which causes a crash.
