Clicking on "My Profile" generates error

[BetterBetsLobos]

First of all, thanks for this project; it makes understanding Silex a lot easier.

When I click on "My Profile" I get the following error:

Twig_Error_Runtime: Impossible to access an attribute ("id") on a boolean variable ("") in "profile.html.twig" at line 29

Any chance you could supply a fix for that?
