Spreadsheet export cannot convert file to txt

[GoogleCodeExporter]

What steps will reproduce the problem?

Call gd_client.Export(entry, export_filename), with a spreadsheet entry using 
code as follows.  The export_filename could be 'foo.txt' having the '.txt' 
suffix. 

  ...
  document_query = gdata.docs.service.DocumentQuery()
  feed = gd_client.Query(q)
  ...
  for entry in feed.entry:
    ...
    gd_client.Export(entry, export_filename)


What is the expected output? What do you see instead?

  It is expected to download the file to foo.txt but raises the following
  exception instead.

  This entry cannot be exported as a different format
  SERVICE ERROR while downloading ZWOpenLog
  Try ranaming the file.



What version of the product are you using?
  gdata (2.0.18)

Please provide any additional information below.

  Line 334 in service.py checks if 'Export' is in the url with
  the following code:

    if export_format is not None:
=>    if url.find('/Export?') == -1:
        raise gdata.service.Error, ('This entry cannot be exported '

  It should also check for 'export' with a lowercase 'e'.


Thank you.
