I have the same situation as romaindu91: no apport dialog, the window freezes and all colours become gray shades: see attachement. If I execute gnome-control-center from the terminal and if I click the "User Accounts" icon, I get a ""libv4l2: error getting pixformat: Inappropriate ioctl for device".
Complete output: ~$ export LANG=en_GB ~$ gnome-control-center (process:11898): Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale.
