[Alvin Penner]

- running Windows XP, Inkscape 0.91+devel r14600 (Jan 17 2016)

Attempting to reproduce the problem reported at:
http://inkscape.13.x6.nabble.com/Differences-in-union-result-between-commandline-and-the-GUI-td4975265.html#a4975268
I get a crash when running the DOS command.
inkscape --file "\windows\temp\exportpath.svg" --select "path3336" --export-plain-svg="\windows\temp\exportplain.svg"
The svg file is attached here.

 crash message is:
** Message: Error: Inkscape encountered an internal error and will close now.
Emergency save activated!

..........................................................

- not reproduced if I remove the path selection command, as in:
inkscape --file "\windows\temp\exportpath.svg" --export-plain-svg="\windows\temp\exportplain.svg"

- not reproduced on Windows 7, Inkscape 0.91 r13725 (Jan 30 2015)

Crash reproduced with Inskcape 0.91+devel r14615 on OS X 10.7.5

Based on tests with archived builds:
- not reproduced with rev <= 13763,
- reproduced with rev >= 13768;
the crash is likely related to the refactoring merge in rev 13767/13768:

* Changelog:

* Commits:
Revision 13767: Merge inkscape-cppify branch

Revision 13768: Replace INKSCAPE.active_desktop() by SP_ACTIVE_DESKTOP for easier grepability

Why is this milestoned to 0.93? Can it be fixed in 0.92.x? Also seems to affect other export file formats. Happens with 0.92.3, too.
