Problem using zipfile.py in ZIP_DEFLATED mode

   Hi all,

  I've been trying to use the module zipfile.py in to archive files in 
a zip archive with compression, and I've  encountered some problems. 
  Here is my code:

       from zipfile import *
      
       #creating my archive
       z = ZipFile('C:\\myZipArchive.zip', 'a', ZIP_DEFLATED)

       #adding my first file to the archive
       z.write('C:\\Test.txt')


And i get this error:

   Traceback (innermost last):
     File "<console>", line 1, in ?
     File "C:\jython\Lib\zipfile.py", line 395, in write
     File "C:\jython\Lib\zlib.py", line 65, in compress

 But when I create my zipfile with no compression with  z = 
ZipFile('C:\\myZipArchive.zip', 'a', ZIP_STORED),  everything is ok...
 Does anybody knows why it fails when trying to compress?

 Thanks,

 Romain
