Hi, over at http://trac.sagemath.org/ticket/12718 I am encountering a strange doctest failure:
This will fail in a fresh instance of Sage:
sage: matrix(QQ['x,y'], 2, 2, [1, 1, 1, 1]) / x
with a TypeError (no error message)
However, if I do:
sage: matrix(QQ['x,y'], 2, 2, [1, 1, 1, 1]) * x
[x x]
[x x]
sage: matrix(QQ['x,y'], 2, 2, [1, 1, 1, 1]) / x
[1/x 1/x]
[1/x 1/x]
everything works. In those examples, x is a symbolic variable.
Any ideas?
