Thanks for trying, but I don't think it's that: my glxinfo is display :0.0 by default and reports that DRI is on, and DISPLAY=:0 blender still crashes. (glxgears doesn't crash on my system with or without that, though others have reported it triggering this bug.)
Since this bug only occurs when DRI is on, I suspect Rene's bug isn't this one at all. I have edited the description to make clearer how to distinguish this from other X crash bugs.
