Bug 567496 – gnome-extra/cinnamon-control-center-2.8.1: cinnamon-settings crashes with signal 11 when clicking the "Color", "Display" or "Networking" button

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description PM 2015-12-03 21:01:43 UTC]

For example, when clicking "Display", the following is printed: 

usr/share/cinnamon/cinnamon-settings/bin/capi.py:53: Warning: invalid cast from 'CcDisplayPanel' to '<invalid>'
  return GObject.new(panel_type)
/usr/share/cinnamon/cinnamon-settings/bin/capi.py:53: Warning: instance of invalid non-instantiatable type 'CcDisplayPanel'
  return GObject.new(panel_type)

and then the whole thing crashes with SIGSEGV in cc-display-panel.c:2526. All the other crashes are similar.

I had the same issues, but after upgrading the gnome-extra/
cinnamon to 2.8.6, the cinnamon-control-center is working fine now.
