nbitcoin new Transaction exception

When creating a new Transaction object from a TxIn.PrevOut.Hash, I have found a case where an exception is thrown. The second transaction of block 170 has a TxIn with a PrevOut hash for the following transaction:

0437cd7f8525ceed2324359c2d0ba26006d92d856a9c20fa0241106ee5a597c9

Using this hash new Transaction(input.PrevOut.Hash.ToString()); throws an EndOfStreamException with a message “no more byte to read”

And a stacktrace:

at NBitcoin.BitcoinStream.ReadWriteBytes(Byte[]& data, Int32 offset, Int32 count) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.cs:line 296 at NBitcoin.uint256.MutableUint256.ReadWrite(BitcoinStream stream) in e:\Sources\NBitcoin\NBitcoin\UInt2561.cs:line 42 at NBitcoin.BitcoinStream.ReadWrite[T](T& data) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.cs:line 198 at NBitcoin.BitcoinStream.ReadWrite(uint256& value) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.Partial.cs:line 219 at NBitcoin.OutPoint.ReadWrite(BitcoinStream stream) in e:\Sources\NBitcoin\NBitcoin\Transaction.cs:line 112 at NBitcoin.BitcoinStream.ReadWrite[T](T& data) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.cs:line 198 at NBitcoin.TxIn.ReadWrite(BitcoinStream stream) in e:\Sources\NBitcoin\NBitcoin\Transaction.cs:line 252 at NBitcoin.BitcoinStream.ReadWrite[T](T& data) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.cs:line 198 at NBitcoin.BitcoinStream.ReadWriteArray[T](T[]& data) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.Partial.cs:line 32 at NBitcoin.BitcoinStream.ReadWriteList[TList,TItem](TList& data) in e:\Sources\NBitcoin\NBitcoin\BitcoinStream.cs:line 224 at NBitcoin.Transaction.ReadWrite(BitcoinStream stream) in e:\Sources\NBitcoin\NBitcoin\Transaction.cs:line 1236

I don’t mean to use this site as a bug tracker, I am just curious if anyone is aware of this and knows anything.
