rviz segfault after exception electric 1.6.3 (ros-pkg ticket #5182)

[hershwg]

I believe the root cause of the exception stems from may computer coming up in low-graphics mode after a reboot. I'm running electric on Lucid.

It look like program was exiting already. Here's a patch that prevents segfault
