nao_description uses sensor_msgs but does not declare that dependency in its package.xml. I filled a ticket for that: https://github.com/ahornung/nao_robot/issues/17

Where does sensor_msgs actually come in? I couldn't see any reference in the CMakeLists.txt

It is implicitly used in the one of the headers, @Dirk Thomas's issue links to it.

Typically this a dependency issue. For some reason, catkin/cmake is configuring nao_description before configuring sensor_msgs.

Looking at https://github.com/ahornung/nao_robot I can't see where nao_description would be creating a dependency on sensor_msgs, so my assumption is that you have common_msgs and nao_robot in your workspace, but not tf (and nao_description depends on tf, tf depends on sensor_msgs, but you lack the cmake configuration for tf to find that dependency on sensor_msgs). My recommendation would be to do a source checkout of tf into your workspace, or stop building common_msgs in your workspace.
