error seemingly due to not having a photo

[HarlanH]

some people are seeing this:

TypeError: Cannot read property 'photo_link' of undefined at app.get.res.render.title (/app/web.js:160:36) at callbacks (/app/node_modules/express/lib/router/index.js:164:37) at ensureAuthenticated (/app/web.js:286:39) at callbacks (/app/node_modules/express/lib/router/index.js:164:37) at param (/app/node_modules/express/lib/router/index.js:138:11) at pass (/app/node_modules/express/lib/router/index.js:145:5) at Router._dispatch (/app/node_modules/express/lib/router/index.js:173:5) at Object.router (/app/node_modules/express/lib/router/index.js:33:10) at next (/app/node_modules/express/node_modules/connect/lib/proto.js:193:15) at resume (/app/node_modules/express/node_modules/connect/lib/middleware/static.js:65:7)

This used to work, but appears to have broken.
