[Bionic] [wayland] many gnome applications exit or crash when a file is opened from within

I cannot duplicate this bug with the X session, only with Wayland.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

whatever gedit is doing nautilus shouldn't hit a segfault, not a gedit bug

It just happens in the Ubuntu-Wayland session. It doesn't happen in the default Ubuntu session. Added the wayland tag.

Status changed to 'Confirmed' because the bug affects multiple users.

Even opening archives with File Roller makes Nautilus 3.26.2 crash. So it cannot be a gedit problem.

I edited the title to reflect that.

So all gnome apps make Nautilus crash (in fact opening the file makes Nautilus and the other program crash) while LibreOffice obviously doensn't. What makes opening a file with LibreOffice different.

I wonder if reverting to 3.26.0 would be a good idea? It potentially resolves the problem and the stable branch doesn't add anything too interesting to Nautilus 3.26.

If the problem persists another package update probably causes the problem. So we know at least...

As a normal user (tested under two accounts), nautilus on bionic wayland (ubuntu and gnome) crashes when clicking on any file.
Strangely, as root added with xhost, there's no problem.

Hope it may help.

Another observation: This problem is not limited to Nautilus. Thus going back to Nautilus 3.26.0 will not help.

==Steps to reproduce for other apps==

1) Open nautilus
2) click on the nautilus entry in the top bar (left of "activities".
3) Select "Help"
4) nautilus exits, yelp doesn't come up
5) open polari
6) click on the "Polari" entry in the top bar (left of acitivies.
7) Select "Help"
8) See polari crash
9) Open gnome-control-center
10) See that gnome-control-center will exit/crash, see that yelp doesn't come up

Not all applications crash. Most applications don't offer the possibility to open yelp from the top bar. So those are not mentioned in the list below:
1) Deja Dup, Gnome control center, Nautilus, Polari, Gnome-Disks, Gnome-Photos, gEdit and gnome-logs will crash
2) Gnome Terminal, Rhythmbox, Gnome-Sudoku, Cheese, Gthumb, Gnome-Mahjongg, Gnome-Mines, Simple-Scan, Gnome-Calculator and Gnome-Clocks, File Roller, gnome-screenshot, baobab, gnome-system-monitor and Totem will not.

Is that a Mutter or Gnome-shell regression? Is it going to be fixed upstream? It seems that some (XDG?-) handover between some gnome apps doesn't work as expected and both apps have to exit.

Status changed to 'Confirmed' because the bug affects multiple users.

A proposed fix for this issue has been identified:
https://gitlab.gnome.org/GNOME/mutter/merge_requests/42

I'm closing all the other bug tasks since we don't need them for every affected app.

A workaround for the Wayland sessions is to right-click on the file and select "Open with X" where X is the default app or "Open with Other Application".

I hope this helps a bit.

Mutter 3.28 didn't migrate to the release pocket yet, but I stole it from the proposed pocket and can confirm it fixing the issue.

This bug was fixed in the package mutter - 3.28.0-1

I can confirm this bug is solved with mutter patch too.
