Hi!

Yep. That confirms my conjecture. Right after that line of protocol, there
is a line containing a {{{split}}} statement, and IIRC it originally was
{{{
SelfValues = singular.eval('print(%s)'%DG.name()).split(',\n')
}}}
In the current version, it is
{{{
SelfValues = [t.strip() for t in
singular.eval('print(%s)'%DG.name()).split(',')]
}}}
instead.
Could you test the following, please:
{{{
sage: R = singular.ring(0,'(x,y)','dp')
sage: I = singular.maxideal(3)
sage: singular.eval('print(%s)'%I.name()).split(',\n')
['y^3', 'x*y^2', 'x^2*y', 'x^3']
sage: [t.strip() for t in singular.eval('print(%s)'%I.name()).split(',')]
['y^3', 'x*y^2', 'x^2*y', 'x^3']
}}}
I reckon that on your computer the two lists are different.
Cheers,
Simon
