Hi everyone,

I've just switched to a recent Xorg build (git checkout from last
Friday). I'm using the radeon driver, and DRI seems to work (1900 FPS
with glxgears, about double the rate than with software rendering).
However, when I tried to run a larger GL-based application, I got this

(gdb) bt

  read=0x0) at dri_glx.c:457

Same backtrace occurs with a freshly compiled Freeglut test program.
