Comment(by benjaminfjones):

 Patch applies cleanly to sage-4.6.2.alpha2.

 I get a strange error when giving beta number sequences with the wrong
 number of elements:

 {{{
 sage: Partition(beta_numbers=([6,3,2],[4,1]))

     310         b = beta_numbers[1]
     311         if len(a) <> len(b):
 --> 312             raise ValueError, '%s is not a valid partition, the
 sequences of coordinates need to be the same length'%beta_numbers
     313             # should add tests to see if a and b are sorted down,
 nonnegative and strictly decreasing
     314     r = len(a)

 TypeError: not all arguments converted during string formatting
 }}}

 I was expecting to get a ValueError. I get the same strange error if I
 try:
 {{{
 sage: Partition(beta_numbers=([6,3,2],[4,1,-1]))
 }}}
