Hi mb,
which Sage version are you running? With 2.8.15 as well as 2.9.alpha7
I get on 64 bit Linux:

sage

sage: var('a b c d e f g')
(a, b, c, d, e, f, g)
sage: V=[a,b,c,d,e,f,g]
sage: M=matrix(SR,7,7,[[z^i for i in range(7)] for z in V])
sage: d=det(M)

| SAGE Version 2.8.15, Release Date: 2007-12-03 |
| Type notebook() for the GUI, and license() for information. |
----------------------------------------------------------------------
sage: var('a b c d e f g')
(a, b, c, d, e, f, g)
sage: V=[a,b,c,d,e,f,g]
sage: M=matrix(SR,7,7,[[z^i for i in range(7)] for z in V])
sage: d=det(M)
printing d works in both cases.
if it still fails with 2.8.15 we need to know a little bit more about
your system, i.e. amount of RAM, gcc -v output and so on.
Cheers,
Michael
