Inkscape 0.48 crash converting svg to pdf/tex

[Rui Pedro Cunha]

I have been using Inkscape to convert my images from svg/svgz to tex, so I can include them on Latex.
Now, I encountered a problem with the graphic attached.
The command I use is

inkscape -D -z --file=SVG_FILE_NAME --export-pdf=OUTPUT_FILE_NAME.pdf --export-latex

and it crashes with the message:

"terminate called after throwing an instance of 'Inkscape::Extension::Output::save_failed'

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at www.inkscape.org
with a detailed description of the steps leading to the crash, so we can fix it.
** Message: Error: Inkscape encountered an internal error and will close now.

Aborted (core dumped)"

AFAICT triggered by one problematic SVG element (not created by Inkscape) with insanely huge coordinates:

Similar observation with another PLOT2SVG-generated SVG file:
* Bug #888559 “Inkscape crashes on the attached file, which is fin...”

(see comments 5 and 6)

Attached modified version of 'PI_controller_step_resp.svgz':
- opens ok with 0.48.5, 0.91, 0.91+devel r14202
  (without excessive memory usage in >= 0.91)
- exports to PDF ok (with or without --export-latex)
  using 0.48.5, 0.91 and 0.91+devel r14202

Modification (externally edited in vim) for testing:
Replaced the points of 'polyline31' with a diagonal line across the defined viewBox size:

          <polyline
             points="0,0 512,384"
             id="polyline31"
             stroke-dasharray="2.0,2.0"
             stroke-width="0.5pt"
             stroke="#000000"
             fill="none" />

Thanks! changing the svg worked well importing to latex!
But it would be cool if inkscape could correct this kind of anomalies on files...
