I just compiled Sage 3.2.2 on a Linux 32 bit machine running the
latest SLED distribution. I also have Magma installed on this machine.
When I log in as a user "george" and try to evaluate 2+2 within a Sage
notebook by using Magma, I get the following error message. On the
other hand, Maple works fine.
Traceback (most recent call last):
