When adding source security groups in the security group dialog, OSM adds a security group from another project. Since it's apparently possible to add groups from other projects (which is weird), it's probably best to list security groups by project, then let users select a security group in that specific project. First priority is allowing security groups within the same project, though.
Fixed in r106135.
