That could be. I never installed the fglrx hardware graphics drivers
for this machine, it didn't work and I gave up since I wasn't noticing
any problems with the default drivers. My glxgears only generates ~300
fps.

Renaming those files disables the Object Graphics hardware-accelerated
rendering path. You are not using OG by running the TV command, but I
guess that the drivers are getting loaded anyway somehow.
Anyway, in Linux, those gl_driver.so libraries use whatever OpenGL
libraries and drivers are installed on your Ubuntu installation. The
error message suggests a problem with drivers associated with the
OpenGL libraries. Therefore, the problem may be outside of IDL and in
the graphics drivers installed in the OS.
One direction, which should have been suggested by ITTVIS support,
would be to check out your OpenGL drivers with other applications.
Try running glxgears, which is shipped in that distro. Glxgears is a
simple test program that can be used to see if the OpenGL libs are
basically working. Might try googling around for any known problems
with OpenGL on your particular distro and hardware (graphics
adapter). Look for any driver updates from the graphics card vendor
and/or use the Ubuntu package manager to install alternate drivers.

I continue to follow up to my own post, but in case it helps someone
else, the solution ITTVIS came up with was to try:

This apparently works and if it doesn't I'll follow up again. :)

please report results also here. We can only workaround bugs and real
fixes can be done only by them.

I am actually working with them as well, but I find that often this
newsgroup gets you faster more appropriate answers.

You are sitting quite close to the headquarter of ittvis
"University of Colorado" sounds familiar to me. Isn't it located in
Boulder? I remember it from a cold day in October.
If so why not ringing the right bell?

Just a little more information:
I have tried switching the hardware/software rendering, neither one
has any effect on the crashes.
It crashes at the commandline or using the workbench.
If I set the preferences to have backingstore controled by IDL (option
2), it still segfaults from the commandline, but the workbench seems
to swallow the command happily and do nothing with it.
I'm also getting a warning on the commandline when I do the first tv
command.
IDL Version 7.1.1 (linux x86 m32). (c) 2009, ITT Visual Information
Solutions
Installation number: 100-1461.
Licensed for use by: University of Colorado (MAIN)
IDL> tv, dist(33,33)
% Compiled module: DIST.
unknown chip id 0x9593, can't guess.
Maybe this rings a bell?
Thanks
Matt
