Title:
crashes trying to open the mouse screen
Status in gnome-control-center package in Ubuntu:
Expired
Bug description:
gnome-control-center crashes on ubuntu 23.04 when trying to open the
mouse screen
Steps to reproduce:
1. In GNOME Settings, navigate to the mouse screen. The control center
crashes (i.e., the window closes instead of showing the mouse screen).
2. Start GNOME Settings again, e.g., using GNOME Shell or by running the
following command from the terminal: `gnome-control-center`. The main window
does not show. Instead, the commandline output prints an error message as
follows:
Commandline output:
```
gnome-control-center --verbose
21:10:51.6276 GStreamer-Play[32248]: ERROR: GtkGstPlay: 'playbin'
element not found, please check your setup
[1] 32248 trace trap (core dumped) gnome-control-center --verbose
```
More observations: Note, this happens reproducably. I just recently
upgraded to ubuntu 23.04, which means I am running GNOME 44. I am now
unable to start the gnome-control-center. It happens in wayland and
xorg sessions. I am using an intel x86 laptop, a lenovo thinkpad x1
carbon.
Workaround: The following workaround allows to start gnome-control-
center again, but does not allow to access the mouse panel. In dconf
editor, reset `org/gnome/control-center/last-panel'. The control
center will then open successfully. I think this indicates that the
mouse panel causes gnome-control-center to crash.
Upstream ticket over at GNOME's gitlab project:
https://gitlab.gnome.org/GNOME/gnome-control-center/-/issues/2459
Upstream analysis by Felipe Borges, maintainer of the upstream
project:
> The issue seems to be about Ubuntu packaging not including the needed
dependencies for the GtkPicture videos we now show in the Mouse panel.
> Could you please file this issue downstream in the Ubuntu bug tracker?
