#15830: extracting coefficient x-1 out of symbolic series wrong

Reporter: dkrenn | Owner:
Type: defect | Status: new
Priority: major | Milestone: sage-6.2

{{{
sage: x.series(x==1,10).coefficient(x-1,0)
x
}}}
which is wrong. It should be {{{1}}}, which can be seen by
{{{
sage: x.series(x==1,10)
1 + 1*(x - 1)
}}}
We also have wrong results here:
{{{
sage: x.series(x==1,10).coefficient(x-1,1)
0
sage: x.series(x==1,10).coefficient(x-1)
0
}}}
