This is caused by the UTXO joining code. So we know exactly what is happening except that it should not be happening. The idea of UTXO joining in coinstake is that we try to join small inputs that we can sign with the same key as coinstake. Somehow it seems that an input that can't be signed with the same key was selected to be joined. So the selection is buggy somewhere.
