Hello,

I report this issue on behalf of someone else, I can't use the bug reporter on the Ubuntu machine.

The same issue has been reported by other people on other places:

The user opens gnome-control-center, the main window appears.
The user selects the keyboard tab and click on the arrow to open the keyboard shortcut binding interface.

The user expects the interface for binding keyboard shortcuts to open.

Instead, the main gnome-control-center window closes and outputs the following error in the terminal:

--- output of gnome-control-center ---

(gnome-control-center: 647357): GLib-GIO-ERROR **: 00:31:19.451: Settings schema 'org.gnome.settin
gs-daemon.plugins.media-keys' does not contain a key named 'screenshot'
Trappe pour point d'arrêt et de trace (core dumped)
--- end output of gnome-control-center ---

It was working some time before the update to 1:41.7-0ubuntu0.22.04.4.

Downgrading the package to 1:41.4-1ubuntu13.2 doesn't fix the issue.

Regards.

Thank you for your bug report, could you give the output of

$ dpkg -l gnome-settings-daemon-common

and then start gnome-control-center and do

$ cat /proc/`pidof gnome-control-center`/maps | grep schemas

Hello,

could you get a gdb backtrace as described on https://wiki.ubuntu.com/Backtrace ?

[Olivier Dierick (o-dierick)]

Hello,

Here is the output of gdb gnome-control-center.

After clicking on the button to access keyboard shortcut, gnome-control-center didn't close but triggered the 'not responding' window, and I clicked 'close' before continuing with the 'backtrace full' gdb command.

Regards.
