Slic3r hangs forever on "0.5mm-thin-wall.stl"

[daid]

When I run slicer 0.7.1 with the following parameters:
slic3r --nozzle-diameter 0.4 --print-center 100,100 --z-offset 0 --gcode-flavor reprap --filament-diameter 2.89 --extrusion-multiplier 1.00 --temperature 0 --travel-speed 150 --perimeter-speed 50 --small-perimeter-speed 50 --infill-speed 50 --solid-infill-speed 50 --bridge-speed 50 --bottom-layer-speed-ratio 0.5 --layer-height 0.2 --first-layer-height-ratio 1.0 --infill-every-layers 1 --perimeters 2 --solid-layers 3 --fill-density 0.2 --fill-angle 45 --fill-pattern rectilinear --solid-fill-pattern rectilinear --retract-length 0 --retract-speed 30 --retract-restart-extra 0 --retract-before-travel 5 --retract-lift 0 --cooling --min-fan-speed 100 --max-fan-speed 100 --bridge-fan-speed 100 --fan-below-layer-time 20 --slowdown-below-layer-time 10 --min-print-speed 10 --disable-fan-first-layers 0 --fan-always-on --skirts 1 --skirt-distance 6 --skirt-height 1 --scale 1.0 --rotate 0 --duplicate-x 1 --duplicate-y 1 --duplicate-distance 6 ./5573/0.5mm-thin-wall.stl
It hangs forever on the first step (Processing triangulated mesh)

The STL comes from http://www.thingiverse.com/thing:5573

I tried that, and it completed the job after 35.1 seconds. Can you please retry with a recent version or, better, git HEAD?
