canonical-certification-server tracedumps when attempting to submit results

After a test run, I ran into a minor issue and a major issue when trying to submit results.

First, the minor issue: I had to hit 'y' twice to get plainbox to prompt me for the SecureID

The major issue is that after I entered the SID, pain box crashed with a traceback. here's the output showing both:Saving submission file to /root/.local/share/plainbox/submission.xml
View results (HTML): file:///root/.local/share/plainbox/results.html

Submit results to certification.canonical.com? [y, n] y
