Anybody else seeing with rqt + rviz: adding camera and it crashes with segfault?
rqt and the adding rviz and then adding a camera and it crashes with segfault for me. Anybody else seeing that? I am using groovy and latest debs on Uuntu 12.04.
Running with gdb python and "run /opt/ros/groovy/bin/rqt":

@TommyP can you run rqt_rviz in a debugger (see here for gdb for example) and send us the output when crashed again?
Also, what versions are you using? For example, what do these commands return?
dpkg -p ros-groovy-rqt
dpkg -p ros-groovy-rqt-rviz
dpkg -p ros-groovy-qt-gui-core
dpkg -p ros-groovy-rviz
Without seeing these outputs I can't tell if it's the same but a ticket was opened and already closed a month ago, which should be already included in the latest debian pkg (eg. my ros-groovy-rqt-rviz is 0.2.8-0quantal-20130216-1454-+0000. Precise version shouldn't be that different). If yours is old, run these commands.

I cannot reproduce the error at home. Will check more at my work computer tomorrow. The version of for example ros-groovy-rqt-rviz at my work computer is 0.2.8-0precise-20130205-1933-+0000 which seems to be the latest version available for precise (had the same version on a computer i updated now),

I added what gdb says but it was not so informative.

Hm, I'm not sure either...it would be ideal to figure out the difference b/w your 2 machines where only 1 causes the issue, before opening a ticket here https://github.com/ros-visualization/rqt_robot_plugins/issues (I think rqt_rviz instead of rviz is the starting point for this ticket).

One difference is that the one with the problem is 32-bits and the one without problem 64-bits. But you are right it might be something strange with my machine if nobody else see the problem. I will try to look into it more deeply after the weekend.

Clearing ROS_PACKAGE_PACK and sourcing /opt/ros/groovy/setup.bash solved the problem. Doing source devel/setup.bash in my catkin workspace and the problem appeared again. I cannot see anything obvious that can cause the seg fault. Any ideas about what to look for?

Yay you made it! However I'm still not sure..If you can reproduce it by manipulating ROS_PACKAGE_PATH and you're sure nothing is wrong in the setting that yields the problem, I think it's worth ticket.
