crash with OpenSCAD extention

[Frank Bouwens]

Inkscape crashes when I process certain SVG-files (that are made with Adobe Illustrator) with the Paths-to-OpenSCAD-plugin.

Plugin download:
http://www.thingiverse.com/thing:25036
download zip-file.

Steps to reproduce:
(first time only:)
- paste extention-files in: ~/.config/extentions/
- restart Inkscape
(always:)
- open the file Tux.svg
- go to Extentions --> Generate from Path --> Paths to OpenSCAD
- Click the apply-button in the extention window.
- The plugin should now generate an .scad-file.
- The program crashes when using an SVG-file that was made with Adobe Illustator.

Attached:
Tux.svg (made with Adobe Illustrator)

gdb.txt (output from gdb)

I use Ubuntu 12.04 LTS and installed Inkscape using the Ubuntu Software Center.
The version is: Inkscape 0.48.3.1 r9886

Workaround:
- open the Tux.svg
- press Ctrl + A, press Ctrl + C
- File --> New
- press Ctrl + V
- go to Extentions --> Generate from Path --> Paths to OpenSCAD
- Click the apply-button in the extention window.
- The plugin will now generate an .scad-file, without crashing.

Based on the information provided:
- Inkscape 0.48.3.1 r9886
- crash with "foreign" SVG files, but ok with SVG files based on Inkscape's own default template
- backtrace

this is another duplicate of the known regression in Inkscape 0.48.3.1 (which affects all script-based extensions, not just the one to export to OpenSCAD):

Forgot to add: any feedback about whether the known workaround "worked" for you or not would be appreciated.

The workaround works for me.
(The program does not crash and the .scad-file is correct)

Thanks !

Good to hear (the regression in 0.48.3.1 is annoying, and we are sorry that it had slipped our attention until after the release. Inkscape 0.48.4 does have a proper fix, but I have no idea whether Ubuntu will upgrade the Inkscape package they offer for Ubuntu 12.04, or at least consider to backport the fix).

Thanks for reporting back!
