HDF5 GetProjectionRef returns NULL sometimes

[warmerdam]

I'm working with a HDF5 dataset with Gdal 1.8.0, I open it with the HDF5Image driver. The image metadata is read OK from what I can see, but when I want to execute the GetProjectionRef() method, it returns null, even if the documentation says it wouldn't return any null pointer.

I've traced the null pointer to HDF5ImageDataset::CreateProjections(), in line 562 it reads

_______________________________________________________________________
poH5Objects=HDF5FindDatasetObjects( poH5RootGroup,  "Latitude" );
    if( !poH5Objects ) {
	return CE_None;
    }
_______________________________________________________________________

Since my HDF5 file doesn't have a "Latitude" dataset, the function returns without setting the pszProjection variable, it remains null and is never being set as an empty string, as the GetProjectionRef consist only in:

________________________________________________________________________
const char *HDF5ImageDataset::GetProjectionRef( )

{
    return pszProjection;  //
}
_______________________________________________________________________

Fixed in trunk (r22340) and 1.8 branch (r22341).
