[Users] 500 Internal Server Error when provisioning via Foreman (using nightly build)

All, I'm using oVirt 3.4.0-0.2.master.20130925104201.git8ab6304.el6 on CentOS 6.4 as a compute resource for Foreman (1.2.2, also running on CentOS 6.4). When I attempt to provision a machine, I get a 500 server error. Logs are posted below: https://gist.github.com/andrew-timmes/d41f465d2c25af5905c8 It looks similar to the issue that Andrew Lau reported in August ( http://lists.ovirt.org/pipermail/users/2013-August/015693.html) but I'm still seeing the issue in the nightly build. Any ideas? Thanks, Andrew Timmes
