I started seeing this problem after updating today (2012-03-19). g-s-d
crashes every time I try to use the hotkeys to adjust the keyboard
backlight brightness. I see lines like the following in syslog:

Mar 19 20:55:17 ubuntu-mba kernel: [  250.180733] gnome-settings-[4019]: segfault at f0 ip 00007f9dc774235b sp 00007fff0cedffe0 error 4 in libmedia-keys.so[7f9dc7735000+25000]
