COT version: 2.2.0 (installed via pip/python2.7/centos7)

When inspecting an OVA file (VMware whitness appliance) the cot info raises an exception:

Thanks for the report!

I verified that the OVF specification allows for multiple ProductSection elements, so this is indeed a bug. Can you provide your complete OVF XML content for me to develop a fix against?

Duplicate of #73, but I'll leave this open separately until the submitter replies.
