Under Ubuntu 17.10 I find that Evince (3.26.0-1) often fails to open when I'm logged on using Wayland. There's no problem using X.
The error is very simple. I double click a PDF file in my file manager and expect it to open in Evince (Document Viewer). And mostly that's what happens, but after having opened a few files, it just stops working for some files.
The error seldom occurs with the first PDF file I open after a reboot, but after I've opened a few files, the error pops up, but only for some files. Some files I can click and they open in Evince each time, whereas other files will never open in Evince. They open fine in other applications and under X.
When I try to open the file from the command line, I get the following error message:
pinnerup@ergi:~$ evince Dropbox/Litteratur/Sprog/Græsk/Beekes\ \&\ van\ Beek\ –\ Etymological\ Dictionary\ of\ Greek.pdf
Gdk-Message: Error 71 (Protocol error) dispatching to Wayland display.
If I rename the file (e.g. by adding the number "2" to the file name), make a copy or move it to another directory, it opens without problems. However, after some time the renamed or new file will fail to open with the same error.
Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https:/
