Precondition failed in PeerGroup.selectDownloadPeer

I get quite a lot of these exceptions reported, using bitcoinj 0.10:

These exceptions still happen on a regular basis with bitcoinj 0.11. I've also 
seen

Hive sees this too. Logs would be really useful. I'll add more asserts.

• Changed state: Accepted

In this log you've got loads of the first exception and some of the second.
