compiz crashed with SIGSEGV in std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string()

[Edward Donovan]

This crash happened in the wake of changing a setting in CCSM, then reverting it. That seemed to go fine, and compiz restarted each time. The crash was about half an hour later . Maybe that's way off; I just associate CCSM with starting trouble, by now. :-/ Whether that was related, at any rate, I hit Ctrl-Alt-Tab, to switch to a window in another workspace. A minute later I hit it again to switch back and the screen was unresponsive. Compiz restarted and apport came up.

Launchpad offered so many possible dupes that I didn't know what to choose. So I'm filing it, and hoping the retracer may help with that. Thanks.
