Gazebo Segfaults in Travis-CI [closed]

edit

Edit: Simpler question, core of issue: How to run Groovy pr2_gazebo's pr2_table_object.launch in Travis?

The command: roslaunch pr2_gazebo pr2_table_object.launch gui:=false

Here is the full output.

Here is where it gets bad:

Googling leads me to different issues. Any Gazebo experts in the house?

Original post:

I'm hoping to integrate our ROS project with Travis-CI and run end-to-end tests automatically.

The project depends on many heavyweight stacks/packages, including gazebo and pr2_object_manipulation.

It successfully installs the (many) dependencies and builds. However, once I start running the tests, things seem to freeze up; the nodes don't start launching, and it looks like components of gazebo might be failing. However, I'm not sure.

Here's the log of the most recent run on Travis. I'm not an expert (by a very long shot) of gazebo so I can't tell if something really obvious is failing, or if it's even gazebo at all. Perhaps something even more subtle is preventing other nodes from launching? (The gazebo I'm trying to bring up is just pr2_table_object.launch)

I guess my question is, does anyone have experience using Travis to run a heavyweight stack like this and can point me to a working setup? Or is anyone experienced enough with gazebo / general ROS mayhem to see what's going on?

I'd be extremely appreciative of any help.
