On our case this not harmless at all. We have searched what cause distribution problems when network link goes down and up. On our setup we distribute each computer as /32 route and on some cases when nic hang and reset it self or link goes down we lost /32 routes and it get fixed when we restart bird. 30.9.2011 9:00, Ondrej Zajicek kirjoitti:

BTW, there is a similar (but mostly harmless) bug not related to NSSA - if an interface appears and there is a static route configured that goes through that iface, the static protocol receives the iface notification and generates the route, which is propagated to an ospf protocol before the iface notification, so gw is not found and the route is propagated without one. That sounds like it might be what I'm seeing (see mail entitled "Directly connected interface redistribution problem" - yes I will get you the debug output you wanted, the test environment got rebuilt before I could get it), as what we're doing is redistributing static routes.
Do you have a fix I could try? May be, but in my case the route is propagated, just without explicit forwarding address (so the propagating router is used as one, which is OK). I don't have a proper fix for that, it is a bit tricky problem. For a workaround it might help to reorder protocols in config file (OSPF before static, you can check in log file whether OSPF gets iface notifications before static).
