 Hi, an undocumented ABI change is present in numpy 1.6.1.  This at least
 affects the Scientific.IO.NetCDF module.  numpy should get an ABI bump for
 this.

 So for Scientific built against numpy 1.5.1, the following demonstrates
 the problem:
 {{{
 apt-get install python-scientific python-netcdf
 python -c "import numpy as np; import Scientific.IO.NetCDF as nc; ncf =
 nc.NetCDFFile('t.nc','w'); ncf.createDimension('dim2', 2);
 ncf.createDimension('n',2); sym =
 ncf.createVariable('d','c',('n','dim2')); sym[:] = [' C', ' O']; print
 sym[:]"
 Traceback (most recent call last):
   File "<string>", line 1, in <module>
 ValueError: could not convert string to float: C
 }}}
 you should get:
 {{{
 [[' ' 'C']
  [' ' 'O']]
 }}}

 This is from debian bug report:
