Description

Older version of Sage was able to say when it couldn't compute Galois group. However, in 5.4,

NumberField?(x21-2, 'a').galois_group(type="pari").order()

gives answer 252, but with

NumberField?(x22-2, 'a').galois_group(type="pari").order()

I got

Error, the variable '_s_' must have a value

I guess this relates to kash interface.
