Description

Currently the nodata value on an existing GDALBand can not be deleted once its set. This can lead to problems when warping rasters that do not have a nodata value. The warp process "copies" the nodata value to the new bands, if the value of the original is None, the warping fails. So this patch is somewhere between a feature and a bug.
