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

(unity-control-center:4394): unity-control-center-WARNING **: Could not load /usr/share/themes/Adwaita/index.theme: No such file or directory

(unity-control-center:4394): GLib-GObject-CRITICAL **: g_object_unref: assertion 'G_IS_OBJECT (object)' 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):

(unity-control-center:4454): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed

(unity-control-center:4454): Gtk-CRITICAL **: gtk_radio_button_set_group: assertion '!g_slist_find (group, radio_button)' failed
