``` python
raise DropPacket("Invalid packet size (there are unconverted bytes)")
```

the above raise occurred, so the signature was not where it should be in a standard introduction-request.  This usually indicates that there were bytes left in the packet after the conversion, though perhaps there is something else going on this this case.

According to community/search/conversion.py there are a few bytes added ```pack('!IBH',...```.  These seem to be the additional bytes.
