Sorry for the late reply, I was occupied with some work. 

Today I tried the latest version of mayavi2 on an amd64 bit machine,
and it works fine for me. 

varun at debian:~$ uname -a
Linux debian 2.6.22-3-amd64 #1 SMP Sun Nov 4 18:18:09 UTC 2007 x86_64 GNU/Linux
varun at debian:~$ dpkg -l mayavi2 | grep mayavi2
ii  mayavi2                              2.1.1-2+b1                 A scientific visualization package for 2-D and 3-D data
varun at debian:~$ 

Sorry, I am not able to reproduce this bug on either i386 or amd64
machine. Could you please try to reproduce this bug on some other
system and report back?

Thanks,
Varun
