Bug#906799: gnome-control-center: crashes or shows blank window when started outside GNOME

Mon Nov 26 11:04:25 GMT 2018

Package: gnome-control-center
Version: 1:3.30.2-1
Followup-For: Bug #906799

Dear Maintainer,

   * What led up to the situation?
     Upgrading the system
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
     apt -u dist-upgrade
   * What was the outcome of this action?
     gnome-control-center won't start
   * What outcome did you expect instead?
     Working gnome-control-center

I can reproduce this bug in the current Debian/testing. gnome-control-center
fails to load as root and as normal user.

Error running as root:

g6# gnome-control-center
**
ERROR:../shell/cc-shell-model.c:458:cc_shell_model_set_panel_visibility:
assertion failed: (valid)
zsh: abort (core dumped)  gnome-control-center

Error running as user:

(gst-plugin-scanner:18923): GLib-CRITICAL **: 11:52:38.154: g_once_init_leave:
assertion 'result != 0' failed

..and so on.

I assume it has to issue with gstreamer somehow. I already deinstalled the old
gstreamer 0.10 leftovers but it did not resolve the problem.

Inside a gnome-session gnome-control-center also won't load. I have tested this
with GNOME session and Enlightenment 0.22 from Debian/testing.

To this message I have attached a small screencast to illustrate the problem.

Thank you kindly for your reply.

Yours Sincerely,

Adrian Immanuel Kiess
