After I upgraded my whole ArchLinux system, I found gnome-control-center unable
to start (other apps can run). I tried to execute it in a terminal and get the following messages.
Perhaps it's just a bug of r300.

I wish it could be solved tomorrow by ArchLinux repo officially--you know how
unstable ArchLinux is, it publishes corrupted packages from time to time and
fix it tomorrow.
However I want you to check whether it's a problem of yours.

The following is the backtrace:
