I've an issue while using unoconv to convert docs to html from a Python script.

It works perfectly when I run the script or the unoconv commands as root, but it fails when I do the same from other user. I had installed Ubuntu 13.04 Server and unoconv packages via apt-get install. I executed the python script as an ordinary (not root) user

>>> from subprocess import call

>>> call(["unoconv","-f","html","-o","/var/www/project/tagging/templates/documents","/var/www/project/media/resume1.doc"])

Error: Unable to connect or start own listener. Aborting.

ls -l give the following:

ubuntu@ip-54-194-10-89:/var/www$ ls -l

total 183184

drwxr-xr-x 24 www-data www-data      4096 Aug 31 15:20 project

project has group and ownership as www-data

If anyone who can help me with this issue it would be appreciated.
