Multilayer EXR Bug? (linux) or my system?

When I try to save as multilayer EXR (Zip, but tried others), Blender exits abruptly with a Segmentation Fault error. The file is created, but unable to be opened in Cinepaint - therefore not completely saved.

Blender 2.45 binary. Not self-compiled or changed in any way from blender.org.

Using Mandriva Linux 2007 Spring with Python 2.5.

Athlon xp2400 NF2 if that makes any difference.

Nothing useful when using the -d switch in command line.

Ideas?
