Old description:
> sage: Partitions(5,min_slope=1).list()
> [[5], [2, 4]]
New description:
The following bug was reported by an humanoid:
{{{
sage: Partitions(5, min_slope=1).list()
ValueError: [2, 4] is not a valid partition
}}}
Even worse (since silent):
{{{
sage: Partitions(5, min_slope=2).list()
[[5]]
}}}

Comment:
I was very puzzled when i saw this ticket, since my Turing tests were not
able to conclude (unless we just reached the singularity). I propose to
reopen the ticket since the report is correct.
By the way, i am not sure the following is a correct behaviour:
{{{
sage: P = Partitions(5, min_slope=2)
sage: Q = Partitions(5)
sage: Q[0]
[5]
sage: Q[0] in P
False
}}}
