Confirming for now as is - the reported issue reproduces in rasterized output based on the same SVG file with Inkscape 0.91 r13725, 0.92.0 r15299, GIMP 2.9.3, and rsvg-convert (librsvg 2.40.13) on OS X 10.7.5, with cairo 1.14.6 and 1.15.5 (git).
Likely, this is the same (or a closely related) issue as already tracked in bug #882236 - the test case provided here though does not expose the same obvious symptoms with cli exports using Inkscape 0.48.5 (unlike bug #882236, and unlike as experienced by the affected user (see forum postings)).
