evince crashed with SIGSEGV in DJVU::MMXControl::enable_mmx()

[Yaron Artzi]

Bug was originally posted manually at: https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1872716

Recap:
I tried to open a djvu file with evince. Instead of opening, the evince window shows for less than a second, and then it crashes.

The djvu file is fine and opens well with evince 3.18.2 on ubuntu 16.04.
When I try to open the file through the terminal (with 'evince <filename.djvu>') I get the output:
"Segmentation fault (core dumped)".

Update:
I installed djview, which had the same error (crash with Segmentation fault message). It was resolved by setting the environment variable LIBDJVU_DISABLE_MMX=1. However, this affected evince somehow, and now I can't reproduce the problem. In fact, now evince can't open DJVU files, and it gives the following error message: "File type DjVu image (image/vnd.djvu) is not supported".

Thanks, that's the same issue than bug #1846785, we should probably SRU that fix to bionic
