Hello guys,

I want to set a nodelet project out of my existing one, so I started the tutorial - Running a nodelet for nodelets. But when I run the line

rosrun nodelet nodelet manager __name:=nodelet_manager

I get the message

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_S_construct null not valid
Aborted (core dumped)

and I have no clue what I can do to solve it.

Google search by searching "basicstring::S_construct null not valid" gives a clear answer, but I do not init a string anywhere.

when i run the launch file refering to the tutorial- Porting nodes to nodelets I get:

roslaunch my_testpkg mynodelet.launch 
... logging to /home/me/.ros/log/0ab06050-0e2f-11e2-a13e-0024d7c57128/roslaunch-me-PC-23795.log
