Bug#787210: evince: 800% zoom does not work in certain dvi documents

[Gabriel Pérez-Cerezo]

Package: evince
Version: 3.14.1-2
Severity: normal

Dear Maintainer,
   * What led up to the situation?
When I open certain dvi files in evince and set the zoom level to 800%, evince
does not show anything.
I tried to replicate this with .dvi files from TeX, but there this problem does
not occur, as the zoom
level is limited to 400 %.
Here is the path that led me to the problem:
I ran `mf beta.mf; gftodvi beta.2602.gf; evince beta.dvi` (file beta.mf
attached) and set the zoom
level to 800%. My mf version is 2.7182818 and my version of gftodvi is 3.0 (TeX
Live 2015/dev/Debian)
   * What was the outcome of this action?
The box displays 611.13%, and the window does not show anything except the
black lines (the gray beta and the text disappeared).
   * What outcome did you expect instead?
The character should have been displayed at 800% zoom.

Best wishes,

Gabriel Pérez-Cerezo
