Re: evince dumps core

[Greg Troxel <gdt%lexort.com@localhost>]

I have evince installed but don't really use it.

netbsd-10 amd64 pkgsrc-current from ~July 2.  Build/install timestamps

evince with no args starts up ok and I can quit it ok.

With a pdf file, I get a crash, and ktrace/kdump point to

I am not svg-clueful but inkspce opens that fine.  That may be a red
herring though; gdb shows

which indeed points into poppler.
