--- Comment #11 from Mamoru Tasaka <mtasaka@xxxxxxxxxxxxxxxxxxx> 2010-03-02 12:00:48 EST ---
Well, while I don't know how to use this package, however when
I try:
- Execute: $ stage /usr/share/stage/worlds/uoa_robotics_lab.world
- After a while, choose "File -> Exit"
- choose "Quit without saving"
Then stage observes segfault, as below:

It seems something wrong on exit handlers is happening. Would
you check this?
