#12129: MPolynomial_libsingular.is_squarefree fails with linear factors
-----------------------+----------------------------------------------------
Reporter: culler | Owner: AlexGhitza
Type: defect | Status: new

{{{
sage: x, y = QQ['x','y'].gens()
sage: f = x*y
sage: f.is_squarefree()
False
sage: f = (x+y)*(x+3)
sage: f.is_squarefree()
False
}}}
This may be related to an inconsistency in the Singular sqrfree function,
which sometimes includes a unit in the square free factorization, but
other times does not.
