Segfault when calling SETCONF

Awwww, ran into one last weekend too. sob

For tor...

% git checkout 5644d92
% git clean -fdx
% make dist-clean; ./autogen.sh && ./configure && make
% mkdir /tmp/tor_test
[made a torrc...]

% cat /tmp/tor_test/torrc 
DataDirectory /tmp/tor_test
ControlPort 1111

% tor -f /tmp/tor_test/torrc

And then...

atagar@odin:~/Desktop/stem$ telnet localhost 1111
Trying 127.0.0.1...

The tor instance fails with...
