"segfault in libgtk-3.so.0.2404.29" when trying to start on wayland

[Random-Chain]

blueman: 2.2.4-1 (latest available in Pop!_OS repo) Distribution: Pop!_OS 22.04 Desktop environment: Gnome - Wayland

When running on xorg, everything is fine. When trying to run on Wayland, blueman crashes on start, or when trying to open the Devices window.

I can't find anything related to Blueman on Wayland or any related open issues, so I don't know if it's not supported or there's something else I need to configure.

Syslog:

Errors I see in Blueman log:

I also have the core dump that I can upload if it's relevant.

Can you disable the gamecontrollerwakelock plugin in the plugin dialog? I don't have any segfaults myself when I run blueman under Wayland (KDE).

[Random-Chain]

I don't see the gamecontrollerwakelock plugin in the list when running on wayland, so can't disable it. Just to check, I logged in to xorg, disabled all plugins, then logged in to wayland with everything off. It still crashes.

I'm also now seeing this assertion that I somehow missed before:

(blueman-applet:29822): Gdk-CRITICAL **: 12:43:02.561: gdk_wayland_window_set_dbus_properties_libgtk_only: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed

Look like I'll have to check this in a VM. Not sure if I can do wayland in a VM...

I can confirm the segfault but also this is very likely a problem with PopOS. The tranmission folks also ran into this, see https://github.com/transmission/transmission/issues/2572. I see menutracker: action unity.-Help missing from the start as well over and over untill it segfaults.

I'd suggest you raise this with the PopOS folks.

You can workaround this by launching blueman-manager with GDK_BACKEND=x11 blueman-manager.
