odt2sxw does not work. I get the following error, which seems to
occur on any .odt file, such as the simple one attached (I created
a new document, wrote "test", and saved):

qaa:~> odt2sxw test.odt
/bin/odt2sxw:778: DeprecationWarning: distutils Version classes are deprecated. Use packaging.version instead.
  if product.ooName not in ('LibreOffice', 'LOdev') or LooseVersion(product.ooSetupVersion) <= LooseVersion('3.3'):

During handling of the above exception, another exception occurred:

AttributeError: ErrCode

Control: retitle -1 unoconv: odt2sdw and odt2sxw do not work: Error Area:Io Class:Parameter Code:26 / soffice.bin process left behind

Same error with odt2sdw.

Moreover a soffice.bin process is left behind:

vlefevre    5923       1 33 17:03 pts/12   00:00:01 /usr/lib/libreoffice/program/soffice.bin --headless --invisible --nocrashreport --nodefault --nofirststartwizard --nologo --norestore --accept=socket,host=127.0.0.1,port=2002,tcpNoDelay=1;urp;StarOffice.ComponentContext

And the consequence is that libreoffice no longer works!
(Running libreoffice has no effect.)
