I've seen a segfault once when running midori in that context (sid, amd64):

[Aug 30 13:12:26] ERROR torsocks[5021]: [recvmsg] Inet socket passing detected. Aborting everything! A non Tor socket could be used thus leaking information. (in tsocks_recvmsg() at recv.c:87)

... but I cannot reproduce it anymore.

I doubt it, as torsocks 2.x is a complete rewrite.
JS, may you please file a separate bug?

David, could you please have a look?
