[sage-devel] Short script dumps me at the command line

Hi,

the following short script dumps me at the command line in Sage 4.8:

M=matrix(2,2,[27, -11, 15, 1])
G,mu = M.gram_schmidt()
M2 = matrix(2,3,[27,-11,21,15,1,9])
G2,mu2 = M2.gram_schmidt()
float(G2[1].norm() - G[1].norm())  > 0

It prints:

WARNING:
********
You or a %run:ed script called sys.stdin.close() or
sys.stdout.close()!
Exiting IPython!

Bill.
