[pr2_simulator] pr2_nav_tutorial.launch and groovy?
hi everyone, I try to follow this tutorial pr2_simulator/Tutorials/BasicPR2Controls but when i try to launch the pr2_nav_tutorial.launch I have several mistakes and warnings like :
[WARN] [WallTime: 1405059934.255135] [152.006000] You've passed in true for auto_start to the python action server, you should always pass in false to avoid race conditions.

I am looking for solution about these errors but nothing is about groovy. So if someone knows if there is another pr2_nav_tutorial. launch file or have an idea to fix it ?
/////edit/////
the process died and It is about Eigen.
move_base: /usr/include/eigen3/Eigen/src/Core/DenseStorage.h:69: Eigen::internal::plain_array<T, Size, MatrixOrArrayOptions, 16>::plain_array() [with T = float, int Size = 4, int MatrixOrArrayOptions = 0]: Assertion `(reinterpret_cast<size_t>(array) & 0xf) == 0 && "this assertion is explained here: " ".org/dox-devel/TopicUnalignedArrayAssert.html" " **** READ THIS WEB PAGE !!! ****"' failed.
I try to check the Eigen website but nothing about that. //////////////////////////// thanks for you help !
I use groovy on ubuntu 12.04 (precise) LTS my laptop is Dell latitude E4310
