Note that you don't have direct rendering here since Intel driver 2.8 doesn't support DRI1, and DRI2 requires UXA/GEM. Such a crash is bad, but upstream probably doesn't care much about non-GEM kernels unfortunately. But you might to bother them at bugzilla.freedesktop.org if you want them to fix this.
