Bug#861736: python-nxs: Cannot save files with nxs python module

[Marc Rosanes <mrosanes@cells.es>]

Package: python-nxs
Version: 4.3.2-svn1921-4
Severity: grave
Justification: renders package unusable

Dear Maintainer,

   * What led up to the situation?

   Run the following python code:

   import nxs
   e = nxs.NXentry(name= "NXtomo")
   e.save("filenamenxs.h5", 'w5')


   * What was the outcome of this action?

   Got the following exception:

NeXusError
Traceback (most recent call last)
<ipython-input-3-05b94b04d656> in <module>()
----> 1 e.save("filenamenxs.h5", 'w5')

/usr/lib/python2.7/dist-packages/nxs/tree.pyc in save(self, filename, 
format)
    866                 root = NXroot(NXentry(self))
    867             if root.nxfile: root.nxfile.close()
--> 868             file = NeXusTree(filename, format)
    869             file.writefile(root)
    870             file.close()

/usr/lib/python2.7/dist-packages/nxs/napi.pyc in __init__(self, 
filename, mode)
    318             else:
    319                 op = 'create'
--> 320             raise NeXusError, "Could not %s %s"%(op,filename)
    321         self.isopen = True
    322


   * What outcome did you expect instead?

An hdf5 file filenamenxs.h5 saved with no exception.

Note: Tried this with debian:stable docker and it worked correctly.
