I also tried installing python-dbg from unstable, and running mayavi2
with that. This is what I got:
abeld at csik:0:~$ which mayavi2
/usr/bin/mayavi2
abeld at csik:0:~$ python-dbg /usr/bin/mayavi2
Traceback (most recent call last):

I don't know whether this cases the segfault when running mayavi2, but
it might be related. (It is quite strange that 'python' can import
that module while 'python-dbg' can't.) I am using the amd64 build of
lenny, are you trying to reproduce this bug on a 32 bit or 64 bit
machine?

Thanks in advance,
Daniel Abel
