I installed the cturtle binaries on our basestation today and when I attempt
to run rviz I get the following segfault:

pr2admin@pr2base:~$ rosrun rviz rviz
[ INFO] [1277171900.979006204]: Loading general config from
[/home/pr2admin/.rviz/config]
[ INFO] [1277171900.979230869]: Loading display config from

/opt/ros/cturtle/ros/bin/rosrun: line 35:  8665 Segmentation fault
$exepath "$@"

There was a post on the list about this a little while ago that suggested
remaking rviz with --pre-clean, but since I built since I installed the
binaries, I wasn't sure of how to correct it.
