err... I don't see reason to create another bug topic so I just place everything I've found in here. If You have found anything or confirmed/reproduced bug. Go ahead write it in here. It might be helpful.
1. Teleporter can't be wrenched. After digging it up. It drops unnamed block (which obviously crash minecraft after placing).
2. Confirming cables does not connect to teleporter. Even further teleporters doesn't get any energy.
