NIO problem with large netcdf dimension

Hi

My netcdf file contains a large one-dimensional data variable. Python
crashes when trying to access the variable as shown below:

Extract of netcdf header:
dimensions:
        side = 2 ;
        xysize = 32477944 ;
variables:
        float z(xysize) ;

Python Code:
>>> import Nio
>>> f=Nio.open_file('05207506.nc')
>>> z=f.variables['z']
>>> d=z[:]
ncvarget: ncid 65536; varid 5: NetCDF: Start+count exceeds dimension bound

However the following code does work:
>>> d = numpy.zeros(z.shape)
>>> d[:-1] = z[:-1]
>>> d[-1] = z[-1]

Juerg
