X crashes when running Minecraft

[Fibonacci]

When trying to run the latest version of Minecraft while using Compiz, almost every single time, X crashes.
I found the following line on dmesg – the last one right after the crash:
[148447.779568] compiz[14930] general protection ip:7f79f4dfa394 sp:7fff47685d40 error:0 in libpthread-2.13.so[7f79f4df1000+18000]

When running Metacity this doesn't happen.
