 After discussion on rock-dev I put that as a ticket to have it in the
 system.

 Given the following data structure
 {{{
 struct Bumpers
 {
     // Number of Bumpers (specific per Robot)
     int nrFront;
     int nrRear;
     // States of Bumpers. See Aria Documentation and/or ArModes.cpp
     // for an Example how to read out these values.
     int front;
     int rear;

     std::vector<bool>  bumpersFront;
     std::vector<bool>  bumpersRear;

     base::Time time;
 };
 }}}
 a segmentation fault is produced when connecting to a port of this type
 via orocos.rb.
 After changing std::vector<bool>  to std::vector<int>  the segmentation
 fault was gone.

 Due to Thomas that is because containers are specialized for bools which
 is not recognized by typelib.

 Janosch proposed using uint8_t or the like as a workaround.

 Using a container with bool in a type should either throw an error at what
 point ever (orogen, runtime exception) or it should work.
