The problem is that you're using a version from 2005.
Axiom is released every 2 months. You can get the version
information from the banner:
AXIOM Computer Algebra System
Version: Axiom (November 2009)
Timestamp: Thursday April 8, 2010
Maybe it was fixed in the latest (or not so latest) downloadable version
of axiom, but it wasn't fixed in the 9.10 Ubuntu distro, which is Axiom
Version 3.9 - but the workaround still works there.
I'll try the distro version again in 10.04 when it comes out April 29 (or
shortly thereafter).
