I'm using a nightly version of Firefox with WebGL enabled and when I try to
visit the page
http://sinisterchipmunk.github.com/materials.html
Firefox crashes and says the crash happened in r600g_dri.so

This is the backtrace I get when I attached gdb to Firefox:
Program received signal SIGSEGV, Segmentation fault.
