The GL in GLBLUR sounds like OpenGL. You probably already know that OpenGL is the 3D graphics acceleration system in Linux. Using this will stress the graphics stack (kernel+Mesa3D+driver) more than ordinary desktop work, and may possibly expose some remaining bugs and/or limitations. My guess is that that is what has happened here. Did apport trigger and create a bug report? If so, you can use apport-collect 516909 to attach the data from the crash to this bug report.
The final 2.6.33 kernel should be out soon. You are encouraged to try that.
