Package: libpoppler28
Version: 0.20.5-1
Severity: normal

When viewing some PDF documents, Evince crashes with the following error
printed to console:

evince: GfxState.cc:4179: void
GfxGouraudTriangleShading::getTriangle(int, double*, double*, GfxColor*,
double*, double*, GfxColor*, double*, double*, GfxColor*): Assertion
`!isParameterized()' failed.
Aborted

This is reported in Ubuntu as the bug (the Ubuntu bug report includes
some links to documents triggering the bug; the particular document
causing the bug on my computer was produced by Adobe PDFMaker 10 from a
MS PowerPoint document)

https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1072129

A patch has been included in the Ubuntu package
(git_gouraud_shading_support.patch) that should fix the bug:

https://launchpad.net/ubuntu/+source/poppler/0.20.5-1ubuntu1

The Ubuntu patch is the backporting of the following upstream commit:

http://cgit.freedesktop.org/poppler/poppler/commit/?id=ae8fc0cbfc6123189e17b3cf1286e0540f181646

The bug should also be fixed in the upstream version (0.22).

I'm using Gnome 3.6 from Experimental. The version of poppler\Evince from 
testing seem not to be affected by the bug (the same document doesn't trigger 
any crash).
