Comment 9 for bug 997595

I ran some tests relating to this bug, I hope this is useful:

----------------------------------------------------------------------

Inkscape 0.48.2, r9818, running on Fedora 13, x86_64:
- the dashed lines in the puzzle are overlaid with thin solid lines (i.e. bug reproduced)

----------------------------------------------------------------------

0.48 devel, r11698, running on Windows XP:
- when exporting from the GUI (File->Save As), the resulting EPS file is fine (!)

same version, running in "cmd":
  inkscape --export-eps=test.eps puzzle_b21d32.svg
results in a crash:
-----
** Message: Error: Inkscape encountered an internal error and will close now.

terminate called after throwing an instance of 'Inkscape::Extension::Extension::
param_not_exist'
-----

----------------------------------------------------------------------

compiled 0.48 devel on Fedora 15, i686: checked out latest source with:
bzr branch lp:inkscape
(checked out Sep 29, ~ 21.39 GMT):
- the horizontal dashed lines still have the solid line through them, the vertical dashed lines are OK (!!)

From the terminal: inkscape --export-eps=test.eps puzzle_b21d32.svg
also results in a crash:
-----
terminate called after throwing an instance of 'Inkscape::Extension::Extension::param_not_exist'
-----
