Andreas,

The default local planner that runs with the navigation stack assumes that
the robot is capable of performing in-place rotations. In particular, the
code that rotates the robot to its goal orientation relies on this
assumption explicitly. There is room to write a local planner that doesn't
make this assumption, but, to my knowledge, nothing like that exists in
public ROS repositories.

Hope all is well,

Eitan
