Stageros crashes frequently on launch
I'm having a recurring problem with stageros crashing immediately on launching any of the launch files in navigation_stage.
I use diamondback, and the nav stack downloaded from the ROS repositories. Occasionally on launching the files in navigation_stage, stageros crashes with the following log:
Once this happens, roslaunch doesn't quit by itself, I have to do a kill -9. Also, subsequent launches of these files leads to stageros crash.
I generally resolve this problem by rebooting by system. This works nearly always.
Any better ideas or suggestions?

That log doesn't seem to contain anything unusual. Is there any error output in the terminal you start the launchfile from?

Nothing except that "stageros has died with log file ~/.ros/logs/<somelog.log>"

Can you try launching stageros in gdb (directions: http://www.ros.org/wiki/roslaunch/Tutorials/Roslaunch%20Nodes%20in%20Valgrind%20or%20GDB) and output the backtrace when it crashes? Use the `bt` command after the crash, get all of the output and then update your question with it (or a link to it).
