[c-nsp] "show rpl unused" bug?

[Hank Nussbacher]

We have encountered a bug on an ASR9010 running IOS-XR v5.1.3
where "show rpl unused" results in a few hits like these:

The following as-path-sets are UNUSED
------------------------------------------
    aspath_191_p1_permit

The following community-sets are UNUSED
------------------------------------------
    378:3300
    378:65379

The following prefix-sets are UNUSED
------------------------------------------
    aspath_191_permit

Yet the IOS config does *not *have these entries.  Can someone point me
at the bugID and version that fixes this?

Thanks,
Hank
