I pulled back the python-six package:
python-six:
  Installed: 1.5.2-1
  Candidate: 1.5.2-1

Now the scheduler and api logs contain the following message:

Status changed to 'Confirmed' because the bug affects multiple users.

[James Page (james-page)]

Zoltan

As Saucy is not longer supported, I'm making the assumption that you have upgraded to 14.04/Icehouse.

Can you check to see if this is still a problem? I'm not seeing any problems in 14.04.

Thanks!

[Zoltan Martha (marthazoli)]

James,

Yes, we already upgraded to Icehouse and the problem does not seem to be present there.
I will set this report to Invalid.
