Connecting an OF13 OVS to the controller lately, I get errors that seem to be related to updating the inventory. Once the switches are connected, a GET on the inventory looks like:

{
"nodes": {
"node": [

]
}
}

This causes the topology manager to go crazy and of course nothing works.

Here's the errors:
