Comment 12 for bug 1106031

Possibly (but not with 100% certainty, due to the nature this bug has manifested itself to me) fixed with Johan's style-related changes in rev 12452, 12470.

Tests with various archived builds on OS X 10.7.5:
- reproduced repeatedly (but not consistently) with revisions 12451 and earlier,
- not reproduced (so far) with r12470 and later.
Repeated tests run via command line (see also comment #3):

$ inkscape -f /usr/share/inkscape/examples/car.svgz --verb="org.inkscape.color.blackandwhite" --verb=FileQuit
