Hi,

I just upgraded to Zenoss 3.2.1 from 3.1.0 by running 'apt-get upgrade'. Immediately after upgrading, I could no longer pull up the device list in zenoss and I saw this error repeat endlessly in zenhub.log:

AttributeError: Networks

    raise AttributeError, id
AttributeError: Networks

Since this instance is a VMware virtual machine I just reverted from snapshot but I can clone it and re-attempt the upgrade.  Any idea what would cause this?

Thanks.
