db_sync error

Hello all,

When I install glance-registry, it occurred a error as below.

Setting up glance-registry (2012.1-0ubuntu2) ...

I check DB and found there was no tables except migrate_version. and migrate_version is 0. So I execute glance-manage db_sync again, it occurred the same error as below.

Maybe the db_sync function got some problems when migrate_version is 0. Please help to clarify. Thanks.

BTW, I check glance-registry.postinst and found the following script. Why glance2012.1 needs to do version-control first when DB does not exist?

if [ ! -e /var/lib/glance/glance.sqlite ] ; then
       su -s /bin/sh -c 'glance-manage version_control 0' glance
fi

Thanks,
