rviz on groovy only works if started in gdb [closed]

edit

I am having serious problems with my Fuerte install since the update released to the repository a few days ago (ros-fuerte-desktop-full 1.0.0-s1367681458~precise, bug report here, but likely filed in the wrong place). So I am trying to begin the process of migrating all of my code to the new build system so I can start using Groovy/Hydro. The problem is that every time I start rviz I get

[ INFO] [1368200619.347291158]: rviz version 1.9.29
[ INFO] [1368200619.347507729]: compiled against OGRE version 1.7.4 (Cthugha)
Segmentation fault

Here is my ogre log, and my system info from the rviz system_info.sh script in Fuerte.

The weird part is that if I run rviz in gdb, everything works without crashing. This is very reproducible; I have never had rviz work outside of gdb, and it has worked every single time inside of gdb.

Does anyone have any suggestions about how to begin debugging this?

EDIT 1

It seems that the comment from @dgossow is likely correct. I was able to produce a core dump from the rviz segfault, and then postmortem that core dump with gdb The backtrace is as follows:

Core was generated by `/opt/ros/groovy/lib/rviz/rviz'.

That obviously doesn't tell me much, but it does point to a problem in my graphics drivers. Running in valgrind provides slightly more useful information. The full log can be seen here. The most relevant part is:

Still doesn't give me much to go off of. Any ideas on how I should proceed?
