Thanks Derelict- the text of the IRC supports this--- text of IRC Sec. 408(d)(3)(B) is as follows
QUOTE
LIMITATION—This paragraph does not apply to any amount described in subparagraph (A)(i) received by an individual from an individual retirement account or individual retirement annuity if at any time during the 1-year period ending on the day of such receipt such individual received any other amount described in that subparagraph from an individual retirement account or an individual retirement annuity which was not includible in his gross income because of the application of this paragraph.
Now what has me scratching my head is why we used to even consider pub 590, when the overriding authority is the IRC… I checked as far back as 2001, and the text for the IRC was the same.
