#5408: Matrix kernel with PARI algorithm passes wrong type
----------------------------+-----------------------------------------------
Reporter: rbeezer | Owner: rbeezer
Type: defect | Status: new
Priority: minor | Milestone: sage-3.4.1
Component: linear algebra | Keywords: kernel, PARI
----------------------------+-----------------------------------------------
Using the PARI kernel algorithm returns a PARI object which is unpacked as
a list with the rows given as tuples. When this is passed to
hermite_form() the object is not of the right type.
{{{
sage: a = matrix(ZZ, [[1,2],[2,4]])
sage: a.kernel(algorithm='pari')
