The patch looks fine, and make test
on my installation of SAGE 4.2.1 returns only one unrelated error, which I include for completeness:
sage -t "devel/sage/sage/plot/plot3d/tachyon.py"
File "/scratch/pancratz/sage-4.2.1/devel/sage/sage/plot/plot3d/tachyon.py", line 297: sage: os.system('rm ' + tempname) Expected: 0 Got: 256
I have attached an additional patch which removes one unused local variable.
