Description

Downstream ticket: https://bugs.launchpad.net/ubuntu/+source/transmission/+bug/1196544

Looks like this is a timing issue where an incoming peer's torrent is removed during an encrypted handshake between reading crypto-provide and IA.

I'm a little concerned that explanation is improbable for the number of duplicates this ticket has in launchpad, but it seems to be the case. For example, https://bugs.launchpad.net/ubuntu/+source/transmission/+bug/1201542 says that the crash occurred right after removing a batch of torrents.

libtransmission/handshake.c's buildHandshakeMessage() should test for this case and, instead of returning a void, return a success flag instead.
