Hello all,

I have tried to get a list of all topics in an rqt plugin with the ros::master::getTopics as suggested here: http://stackoverflow.com/questions/26785675/ros-get-current-available-topic-in-code-not-command

When I have first run my plugin only rosout and rosout_agg was accessible even if rostopic list listed another topics too. After opening a Plugins -> Easy message publisher the another topics also appeared.

I have created a PoC cpp file to test: https://gist.github.com/martonmiklos/44f59cc921858771b4b6dc061e8e29e2

I am running Ubuntu 14.04 LTS, ROS indigo from the apt packages.

Does anyone has any information why the later method is failing? Thank you in advance!
