Haven't heard that before, but it sounds like as good a reason as others I've heard to throw out that nonsense.
I'm not as well versed on this issue of the Hebrew text versus the LXX as others, but it seems pretty clear that the primary reason the RC's and EO are so vehement in supporting the LXX, or whatever version you are talking about, is because they include books that allow for praying to angels, purgatory and some of the other unique beliefs you hold. It's an odd position to hold to since so many of the pre-nicenean theologians rejected those books as Scripture.
