Needs work

Oops, my bad, A patch on top of that is coming up once sage.math is running again.

Cheers,

Michael

Jaap,

a second patch to be applied on top of the other patch is up and should fix the issues. It even passes doctests now on my test box ;)

Cheers,

Michael

Now:

sage -t  "devel/sage/sage/rings/polynomial/multi_polynomial_ideal.py"
	 [39.8 s]
 
----------------------------------------------------------------------
All tests passed!

Cheers,

Merged both patches in Sage 3.2.3.final
