Resolution:
If I try to define a /31 IPv4 prefix of type Subnet in Management -> Address
Space I get the following error:
@
error: Illegal division by zero at
/usr/local/netdot/htdocs/management/subnet.mhtml line 161.

The subnet is created in the database, but cannot be displayed. The exact same
error appears if I select a /31 subnet already defined in netdot.
/31 Subnets discovered by SNMP on routers are added to netdot fine. But again
cannot be "clicked on".
/31 Containers and Reserved work fine.
This is in version 1.0.4. I have a feeling this problem was not present in
1.0.1, but I'm not a 100% sure.
