On my system (ubuntu 10.10 beta) the attached file also gets cropped (and is not subsequently recoverable in inkscape 0.48.0 r9654 by page resizing), possibly because i have the LC_PAPER set to en_GB.UTF-8 in order to get A4 as default. A4 is somewhat narrower than Letter and that's exactly how much the drawing gets (irrecoverably) cropped.
