Xfdesktop not starting

Hello, my xfdesktop is failing to start, given the error that it gives, it seems an issue with the last update of the package glycin, version 2.2.3-1.

$ xfdesktop

For now I have "resolved" by rolling back to the previous version: https://archive.archlinux.org/packages/ … kg.tar.zst
I don't know if this is the correct place where report this issue, if not, let me know,

thanks!

Re: Xfdesktop not starting

Slightly different backtrace, https://gitlab.gnome.org/GNOME/glycin/-/work_items/342

Starting xfdesktop by hand after login, with the same wallpaper, works fine. The crash only happens in the first few seconds of the session, so it looks like a startup race rather than a problem with the image itself.

True?

Re: Xfdesktop not starting

I have a very similar problem with xfdesktop not starting correctly : after login desktop icon blink and then disapear. I got a black background on the desktop.

Launching manually xfdesktop produce a similar trace as shown in post #1.

Long story:
After upgrading this morning, lightdm start working. I restore it by removeing the package and re-install it. Then once I can login the deskop show a fully black background instead of the picture used. The desktop icon blink and then disapear.

After seeing the first post, I downgrade glycin to version 2.2.2 and this fix the xfdesktop problem (desktop icons and image are back).

Re: Xfdesktop not starting

Hi Guzzista, I got the same issue.
Rolling back glycin package, solves the problem for me.

How did you find out that glycin is the problem?
When I start xfdesktop, i missing a stacktrace.
