>From http://www.opengl.org/wiki/Rectangle_Texture:

"Rectangle textures contain exactly one image; they cannot have mipmaps.
Therefore, any texture parameters that depend on LODs are irrelevant when used
with rectangle textures; attempting to set these parameters to any value other
than 0 will result in an error."

Based on this I understand that that setting a value of 0 for
GL_TEXTURE_MAX_LEVEL should not produce an error in this case.

I sent a patch to the mailing list:
