Possibly related: error occurring when processing single-stop gradient definitions (osb swatches) with matrix transforms like this:
gradientTransform="matrix(0,0,0,0,637.81073,-4043.8209)"
The attached variation of the original test case still uses custom swatches for all colors, but exports ok to PDF. The matrix() gradientTransform's had been manually deleted via built-in XML Editor, and unused swatches cleaned up (see preferences).
