In my case (see bug 859723) this happens with Opera and KeepassX whenever I close the application with some of its content in the clipboard. Eg. I copy a password in KeepassX or something on a web page in Opera, then close the application.
I'm attaching the backtrace from bug 859723 for what it's worth. ** Attachment added: "g-s-d crash backtrace when closing Opera" https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/873545/+attachment/2617582/+files/g-s-d_gdb_bt.log -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/873545 Title: No GTK theme applied on login Status in “gnome-settings-daemon” package in Ubuntu: Confirmed Bug description: I just updated to Ubuntu 11.10 - and everything looked perfectly okay - except Nautilus!
