problem with SoWriteAction, ivcat and textures?

[Dennis Mikkelson <mikkelsond@xxxxxxxxxxx>]

  I've been having problems using SoWriteAction.  It works fine in many
cases, but fails in others.  For example, if I load the file
.../models/furniture/table.iv  as part of a scene graph and then try to
write the scene graph using SoWriteAction, I get a Segmentation fault.
In fact, using ivcat on the table.iv file also causes a Seg fault.  The
error shows up using ivcat with other files using textures, such as
.../models/slotMachine.iv, so I originally thought the problem might be
with textures.  However, I modified the Inventor Mentor example
07.1.BasicTexture.c++ to write the scene graph to a file using
SoWriteAction, and it worked fine.  If the problem is due to textures,
it is only a problem for certain textures.

  Has anyone else observed this problem, or is it a problem with my
particular system and configuration?  ( Redhat 6.2 with
openmotif-2.1.30-MLI from MetroLink. )

Thanks,
Dennis
