Bug Description

Am Running off of a 4 GB USB flash drive. I was changing "Image Loading" check boxes. At the moment of the crash I had just clicked to enable the SVG checkbox.

P.S. Please don't remove CCSM from the Repos?? Yes It can cause crashes such as this and in other cases and flat out break systems depending on what you change. But why not have the main developer fix the breakages, or put the options that cause the breaks into an "Advanced Users Only" page or tab? I

 really love tweaking these settings to MY preferences. Such as increasing the animations timing. Cause 120 ms is BARELY enough time to even notice any animation. Much less truely appreciate it for adding to the flare of the system. I also am in Love with the ADD helper plugin. I don't paticularly have ADD, but it does help to focus on what I'm doing, and I enjoy being able to see all the running and open applications behind my currently selected one, as well as the high res wallpaper.

If you do decide to take out CCSM....PLEASE!!!!!! Have consideration of your users to either build the top plugins into the Settings application. OR put a bounty out to have the devs of Ubuntu Tweak or MyUnity to build all more advanced Compiz tweaking options into their apps. As loosing easy access to CCSM will just plain suck, as I have no experience or desire to compile CCSM from source after its removed from the repos.

This bug appears to be the same heap corruption as bug 931201. So I will mark it as a duplicate unless proven otherwise.
