reproduced with your drawing in Inkscape 0.46+devel r22575 on OS X 10.5.8, Python 2.6.2
1) Resetting the preferences to default values (including those for the 'Pattern along Path' extension) and applying it to your example I get the same 'ZeroDivisionError' failure.
2) increasing the number of copies
- Setting 'space between copies' to 1.0 and [x] Live Preview works as expected.
- Lowering the spacing takes increasingly longer:
spacing 0.2: 4.5 minutes of CPU time to calculate and render
spacing 0.1: I canceled the test after letting Inkscape run for 50 min (without crash), it had partially created and rendered the new path but seemed unable to finish.
