A clear and concise description of what the bug is.

In the options menu: display options/anisotropic filter, if you scroll through the options, eventually the game will crash when you get to item 0, "default":

OptionValue "Anisotropy"
{
	0, "$OPTVAL_DEFAULT"
	1, "$OPTVAL_OFF"
	2, "$OPTVAL_2X"
	4, "$OPTVAL_4X"
	8, "$OPTVAL_8X"
	16, "$OPTVAL_16X"
}

You can scroll through the options in either direction. So it will go 8x, 16x, crash or 8x, 4x, 2x, off, crash.
