Thanks David. I just reported the bug to PARI.

The following code crashes (in Sage 8.1 and on CoCalc):
sage: K=CyclotomicField(20)
sage: R.=PolynomialRing(K)
sage: (x^4-1).factor()

But it's working otherwise! Meaning that if I don't pass to the cuspidal
subspace, it appears to be correctly computing slopes. And it is so much
faster than working over Q(zeta_11)...

The following code crashes and asks me to report this as a bug:
sage: Qp = pAdicField(11)
sage: G = DirichletGroup(11,Qp)
sage: omega = G.0
sage: M = ModularSymbols(omega^2,2)
sage: M
Modular Symbols space of dimension 2 and level 11, weight 2, character [4 +
7*11 + 9*11^2 + 5*11^3 + 2*11^4
I'm trying to help develop some code that a group is currently working on
using sage 5.11, and so I need to get a copy of that version of sage on my
laptop. There is no longer a binary file posted and so I need to install
through the source code. I know little about how these things work, and
