Ajenti panel fails to load (Ubuntu 14.04 x64).

Trying a fresh install of Ajenti on a fresh Ubuntu 14.04 x64 VPS from DigitalOcean.

Ran the install as per the automatic install described here. That went all nice and smooth, and when I visit the Ajenti URL, it presents me with the login prompt and accepts the default credentials.

However, it then never progresses past the "spinning gears" page (similar what was posted here). This occurs in both Chrome and Safari.

Running as $ ajenti-panel -v and hitting Ctrl+\ at the appropriate time produces:

I've tried disabling SSL, same error. I've uninstalled Ajenti and Python, still same error. Short of blatting the entire server and starting fresh with a different OS, I'm not sure what else to do.

Any assistance would be appreciated. Thanks!
