Hi,
I was trying to start hector quadrotor demo launch files and keep getting gazebo segmentation faults when the script tries to spawn quadrotor. After some time I have tried to spawn it on my own using these launch files:
roslaunch gazebo_ros empty_world.launch
roslaunch hector_quadrotor_gazebo spawn_quadrotor.launch
But even then the gazebo server crashes with following error:
spawn_model script started
[INFO] [WallTime: 1423382867.059244] [0.000000] Loading model xml from ros parameter

[gazebo-1] process has died [pid 24654, exit code 139, cmd /opt/ros/indigo/lib/gazebo_ros/gzserver worlds/empty.world __name:=gazebo __log:=/home/rokas/.ros/log/25359450-af08-11e4-930f-fcf8ae311424/gazebo-1.log].
The log files after the error is empty, so I can't traceback what happening. But it seems like spawning quadrotor crashes the gzserver.
I have tried using the packages installed via `apt-get` and then tried with latest version of `hector_quadrotor` from github and the problem persists. Maybe some of you will have some ideas on this problem?
