I've done a lot of printf debugging already, the problem occurs before

1346: err = ctx->response_handler(request,response,
ctx->response_baton, pool);

Rather it is back on

1228: status = serf_bucket_response_wait_for_headers(response);

Where the problem manifests itself. The status comes back as 70014
(APR_EOF) which causes us to hit

1244: if (strcmp(ctx->method, "HEAD") != 0 && sl.code != 204 &&
sl.code != 304)

Which segfaults because ctx isn't valid. The debug build *never*
returns APR_EOF on line 1228 so that avoids the segfault.

All the other failing tests besides #78 have a valid ctx so we enter
the block after line 1244 and see the 'svn: Premature EOF seen from
server (http status=404)' error.
