ofImage_gif_grayscale problem

ofImage_gif_grayscale

Seems to have something to do with this:

			if (fif == FIF_GIF) {
				FIBITMAP* convertedBmp;
				if(pix.getImageType() == OF_IMAGE_COLOR_ALPHA) {
					// this just converts the image to grayscale so it can save something
					convertedBmp = FreeImage_ConvertTo8Bits(bmp);
				} else {
					// this will create a 256-color palette from the image
					convertedBmp = FreeImage_ColorQuantize(bmp, FIQ_NNQUANT);
				}
				bool success = FreeImage_Save(fif, convertedBmp, fileName.c_str());
				if (convertedBmp != NULL){
					FreeImage_Unload(convertedBmp);
				}
