I've successfully installed ROS & Gazebo using Homebrew and following the Wiki instructions on my Mac, running Yosemite 10.10.5. Both of these execute ok. But when I try to run rostopic list I'm getting this Python error:

Philips-MBP:install_isolated philipbarile$ rostopic list
Fatal Python error: PyThreadState_Get: no current thread
Abort trap: 6

Any help with a solution would be greatly appreciated.

Below is a full error dump when it crashes. Thanks, Phil

Thanks for the help! I tried to follow the instructions on the link you supplied but was somewhat confused on some of the parameters used in the commands i.e. what is the <problematic_formula> Anyway, I decided to go ahead and start over running ROS under Ubuntu on my Mac using Oracle's VirtualBox
