subprocess.call() raises exception

[GoogleCodeExporter]

What steps will reproduce the problem?
1. create a simple scene with a single cube in blender 2.6
2. export to OGRE
3.

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

This is the error message I see:

What version of the product are you using? On what operating system?

The one from the HG repository. Fedora Linux 16.

Please provide any additional information below.

The blender2ogre script calls subprocess.call(cmd) with these arguments: 
['/usr/local/bin/OgreXMLConverter', '-log', '_ogre_debug.txt', '-e', 
'/home/yxn/src/game/Cube.mesh.xml'], I have verified that the following python 
script works fine with python 3.2.1. Though blender2.6 is using python3.2.2:

import os
import subprocess
import io

subprocess.call(['/usr/local/bin/OgreXMLConverter', '-log', '_ogre_debug.txt',
'-e', '/home/yxn/src/game/Cube.mesh.xml'])

looks like subprocess.call has changed in py3.2.2.
this needs to be fixed.

Can you verify if this happens if you pull the latest HG code?
