Right-click file on desktop > Move to Trash frequently crashes gnome-shell

[Mario Vukelic]

In 19.04 Disco fully up to date. Reproduced on two different machines:

1. Log into Wayland session (did not try with X)
2. touch ~/Desktop/testfile
3. Right-click testfile on Desktop > Move to Trash

-> gnome-shell crashes in around 50% of instances in my case. I did not find out what's the difference. I do run a few other gnome-shell extensions, but all from the Ubuntu repos except for Remove Accessibility.

There are quite some occurrences of org.gnome.Shell.desktop in journalctl, though I didn't correlate yet as the issues seems easy to repro. If you can't repro, pls let me know and I can look for clues.

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

[Carlos Pita (carlosjosepita)]

Also happens in X11 with Ubuntu 19.04. Often moving anything in the desktop to trash restarts the shell or simply hangs.

Thank you for your bug report. Could you trigger the issue, note the time where you had it and add your journalctl log extract from around that moment?

[Olivier Tilloy (osomon)]

I can reliably reproduce the crash about half of the time with the following steps:
 - create a symlink to a folder on the desktop
 - right-click on that symlink and choose the option to send to trash

I have managed to reproduce in a clean and fully up-to-date disco VM, but not in an eoan VM, which suggests the problem was fixed in eoan.

[Sebastien Bacher (seb128)]

Can anyone trigger the issue on 19.10? If not we should probably consider it as fixed in that version

[Mario Vukelic (kreuzsakra)]

I'm the OP and I can't. Thanks

[Sebastien Bacher (seb128)]

Let's close the bug then, thanks!
