Accelerated program crashing on startup
 

I'm running xfree86 4.2.0 with an ATI Radeon 9700 pro with the newest graphics driver installed, but when I try to run a program that requires 3d acceleration, it crashes to the desktop on start-up and displays this error:

Xlib: extension "XiG-SUNDRY-NONSTANDARD" missing on display ":0.0".

Developer Backtrace:
[ 1] /lib/i686/libpthread.so.0 [0x40028e55]
Signal: SIGSEGV [segmentation fault]
Aborting.

Does this mean I should get a newer version of xfree86? Or get a new Xlib?

Does anyone have an idea of what I can do to fix this?
