Recently I have installed Ubuntu 18.04.1 on my laptop (Dell Precision M4700, 16GB RAM), it's quite pure at the moment. The problem is that Evince 3.30.0 produces segmentation fault (core dumped) on launch. It is happening since the system was installed and purging and reinstalling (through Synaptic as well) did not help. Any ideas how to make it work?

I entered

~/.local/share/gnome-shell 

to check what is in the extensions folder - it happens, there is no such folder (no folders at all), 'ls' in /gnome-shell produces:

application_state

Swapping to another (freshly made) user and running Evince there produces the same result.

Running sudo debsums -s provided output:

debsums: changed file /usr/share/X11/xkb/symbols/pl (from xkb-data package)

which is a file I have edited manually. Having it replaced by the original file (and deleting that new user I made) I got some more output from running evince in terminal:

Attempting to read the recently used resources file at 

'/home/january/.local/share/recently-used.xbel', but the parser failed:

Failed to open file “/home/january/.local/share/recently-used.xbel”: 

Permission denied.

Segmentation fault (core dumped)

This file had permission to read and write for my user, but had no permissions for my group. I edited these permission to provide my group with read an write and now it's just Segmentation fault like before when I run Evince.

I purged Evince again also with Synaptic to install version 3.28.2-1 (through Synaptic). First of all I encountered an error when I used GUI Apply button when trying to install Evince again:

E: Unable to correct problems, you have held broken packages.

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

E: Unable to correct dependencies

E: Unable to lock the download directory.

The error did not appear though when I selected Edit->Apply Marked Changes. Reinstallation still produces Seg.fault when running Evince.

Running sudo evince I get:

No protocol specified

Unable to init server: Could not connect: Connection refused

Cannot parse arguments: Cannot open display: 

As things happen out of random sometimes I managed to get an error from evince in GUI (splash would you call it?), sorry for it being quite big I wanted to include all possible data.

Running fsck in recovery root command line yielded no errors.

I did memtest a couple of days ago and then I did one after doing the fsck, receiving this result:

From the comments...

We've got a malloc error with Evince.

Step #1:

To check the file system on your Ubuntu partition for errors...

• boot to the GRUB menu


• choose Advanced Options


• choose Recovery mode


• choose Root access


• at the # prompt, type sudo fsck -f /
  


• repeat the fsck command if there were errors


• type reboot
  

If for some reason you can't do the above...

• boot to a Ubuntu Live DVD/USB


• start gparted and determine which /dev/sdaX is your Ubuntu EXT4 partition


• quit gparted
  


• open a terminal window


• type sudo fsck -f /dev/sdaX # replacing X with the number you found earlier


• repeat the fsck command if there were errors


• type reboot
  

Step #2:

Boot to the Ubuntu Live DVD/USB and run memtest for one complete pass.

Update #1:

Memtest showed a memory failure, as I suspected. Remove or replace some RAM sticks.

Got the same error since yesterday on evince 3.28.4 (exactly as described), no memory faults, devs, check what were the mods since yesterday both on evince and 4.15.0-43-generic 64-bits. Will check as well.
