crashed on tr_dh_secret_derived

[zer09]

I am trying to download sdi-tool but after adding the torrent, transmission will crash.
I also have a crash report with a core dump.

Process 7180 (transmission-gt) of user 1000 dumped core.

I wasn't able to reproduce so please upload the core dump somewhere.
