Comment(by jdemeyer):
The problem lies with the conversion between PARI and Sage:
{{{
sage: K.<a> = NumberField(x^2 - x - 1)
sage: pari_ideal = pari("[5, [2, 1]~, 2, 1, [2, 1]~]")
sage: pari(K.ideal(pari_ideal)).debug()
[&=00000000049f97b8] MAT(lg=3):2600000000000003 00000000049f97a0
00000000049f9770
mat(1,1) = [&=00000000049f9788] INT(lg=3):0200000000000003
(+,lgefint=3):6600000000000003 0000000000000005
mat(1,2) = [&=00000000049f9758] INT(lg=3):0200000000000003
(+,lgefint=3):4000000000000003 0000000000000002
mat(2,1) = gen_0
mat(2,2) = [&=00000000049f9740] INT(lg=3):0200000000000003
(+,lgefint=3):4000000000000003 0000000000000001
}}}
