[vtkusers] vtkImageViewer buggy?

[David Gobbi]

Were any error messages printed?  The most likely things that
could cause a crash are:
1) wrong filename or file couldn't be read (VTK can only handle
   some uncompressed TIFF files, and even though it will print
   an error message your program will probably still crash).
   I would recommend against using TIFF with VTK.
2) bad OpenGL or Mesa on Linux (what version of Linux are you
   using?)

Upgrading to VTK 3.2 is unlikely to fix either of these, but I
would recommend that you upgrade to VTK 3.2 in any case because
it is a pretty solid, up-to-date release.
