Comment:
Added that exception clause. Now the same example raises another
NotImplementedError, but one that gives more information. Essentially,
computing ratios in that given ring Q is not possible, which is a problem
in LinearMatroid._line_ratios().
So what is the policy here? Should has_line_minor() test if computing
inverses is possible before handing the problem down?
