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?

TommyP ( 2013-02-22 04:19:46 -0600 )edit

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.
