Crash on opening an EMF

[Andreas Beeker]

Inkscape version: Inkscape 0.92.3 (2405546, 2018-03-11)
System: Linux 4.15.0-36-generic #39-Ubuntu SMP Mon Sep 24 16:19:09 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The attached file causes a segmentation fault.

In case you want to do a mass test, I have a common-crawl / govdocs corpus of ~200000 emf files, which I currently use to implement an EMF parser/renderer.
