Blank Contact List After Upgrade to 2.6.0

I just updated from Spark 2.6.0 RC2 to 2.6.0. I am running Windows 7 SP 1. Now when I launch Spark and log in my contact list is empty and the following message is posted to the error log

I am not using shared groups. The only thing unusual about my groups is that I am using subgroups e.g. TopGroup::SubGroup. I don’t have any subgroups deeper than one level. Any help would be greatly appreciated.

I uninstalled it, then installed the latest 2.6.1 nightly and the contacts and groups now show.
