Hi,

I'm working with Sage 6.3 on a macbook pro with OSX10.8.5.

When I use some function of the module sr.mq 
(http://www.sagemath.org/doc/reference/cryptography/sage/crypto/mq/sr.html), 
I have a bug:

sage: sr = mq.SR(1,1,1,4, gf2=True, polybori=True)
sage: K = sr.base_ring()
sage: K
Finite Field in a of size 2^4
sage: a = K.gen()
sage: K = [a]
sage: P = [1]
sage: F,s = sr.polynomial_system(P=P, K=K)
sage: F.groebner_basis()
---------------------------------------------------------------------------
RuntimeError                              Traceback (most recent call last)

What the matter with this?

Thank you for your help
