Segmentation Fault when Opening Appearance

[Jonah Bron]

When I open unity-control-center and click on Appearance, most of the time it crashes as soon as it finishes loading the wallpaper thumbnails. Sometimes, the command-line output is as follows:

-------------------------------------------------------------------------

(unity-control-center:4394): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

(unity-control-center:4394): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

(unity-control-center:4394): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

*** BUG ***
In pixman_region32_init_rect: Invalid rectangle passed
Set a breakpoint on '_pixman_log_error' to debug

Segmentation fault (core dumped)

-------------------------------------------------------------------------

And sometimes it looks like this (note the corruption error at the end):

-------------------------------------------------------------------------

Status changed to 'Confirmed' because the bug affects multiple users.

Exactly the same issue on my computer. Ubuntu 14.04 x64

Itried the folowing:

Nothing to do...

Same problem, using Ubuntu 14.04 64bit:

 unity-control-center

(unity-control-center:4387): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

(unity-control-center:4387): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

(unity-control-center:4387): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

(unity-control-center:4387): unity-control-center-WARNING **: Could not load /usr/share/themes/Adwaita/index.theme: No such file or directory
Segmentation fault

[David (daharper)]

Just to add, it crashes for me before I see the Appearance settings.

For example:

* Right click and select Change Desktop Background, I see nothing

* Within System Settings, if I click Appearance, the settings UI crashes immediately.

[Pelle van der Scheer (pellesimon)]

Adwaita theme has nothing to do with it (Can be installed with gnome-themes-standard-data)

Same problem here, segfaults on unit-control-center appearance

Same problem.

First error:

(unity-control-center:20928): unity-control-center-WARNING **: Could not load /usr/share/themes/Adwaita/index.theme: No such file or directory
Segmentation fault (core dumped)

After installing gnome-themes-standard:

(unity-control-center:21272): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed
Segmentation fault (core dumped)

Ubuntu 14.04 upgraded from 13.10, x64, NVidia graphics. Considering re-installing 14.04 if Appearance works in live CD.

[Naftoli Gugenheim (naftoligug)]

Workaround: I rolled back to this version: https://launchpad.net/ubuntu/+source/unity-control-center/14.04.2-0ubuntu1/+build/5587415
Downloading it and installing it with dpkg -i fixed it for me.

[Eivar Montenegro (e.mont01)]

Naftoli solution worked for me on Ubuntu 14.04.1 LTS

[David (daharper)]

I get this after the following steps:

sudo add-apt-repository ppa:inizan-yannick/mono
sudo apt-get update
sudo apt-get dist-upgrade

libglib2.0-0 libglib2.0-0:i386 libglib2.0-bin libglib2.0-data

I accept the updates, then the problem happens.

Just to be clear, everything is fine until I upgrade the mentioned packages.
I have re-installed and repeated this process.
