Right-clicking in Chrome's "Save As" dialog crashes xdg-desktop-portal-gtk

[Ohad Lutzky]

Ubuntu version: Ubuntu 21.04
xdg-desktop-portal-gtk version: 1.8.0-1
google-chrome-stable version: 94.0.4606.61-1

Reproduction:

1. Open Google Chrome - this has been occurring for several months, so different versions, but currently the one I have installed is: 94.0.4606.61 (Official Build) (64-bit)
2. Right-click on any page, click "Save As" (or download a file, which opens the same dialog)

Expected behavior: A context menu with items such as "Open With File Manager", "Rename", etc.
Actual behavior: "Save As" dialog is closed, and apport is triggered for /usr/libexec/xdg-desktop-portal-gtk (I *think* I attached a stack trace here).

Other apps (firefox, gedit) work as expected here, the problem appears specific to Chrome - but Chrome isn't crashing - xdg-desktop-portal-gtk is. Therefore I'm starting by filing a bug report here.

Unfortunately Chrome isn't reporting anything to stdout/stderr about this (only some unrelated messages about bluetooth).

Note: I've attached /var/crash/_usr_libexec_xdg-desktop-portal-gtk.1000.crash. However, /var/crash/_usr_libexec_xdg-desktop-portal-gtk.1000.uploaded exists, with contents 68511cc2-2374-11ec-b3f5-fa163e6cac46. I don't see that this actually opened a bug anywhere though.

Thanks, the errors report for the ID lists has a signature similar to https://github.com/flatpak/xdg-desktop-portal-gtk/issues/315

FWIW, as opposed to https://github.com/flatpak/xdg-desktop-portal-gtk/issues/315#issuecomment-695995792, this does not reproduce for me in other apps when unsetting WAYLAND_DISPLAY.

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