I cannot reproduce your problem
>From your log, the SEGV is caused in gtk_show_all() with gail and depends on
the ibus lookup window.
Which characters did you try to show in Chinese ?

Now ibus-1.3.99.20110419-9.fc15 is available:
# yum install --enablerepo=updates-testing ibus

It seems LibreOffice uses GTK2 but gnome-settings-daemon is based on GTK3.
I guess if you remove
/usr/lib64/gnome-settings-daemon-3.0/gtk-modules/at-spi2-atk.desktop, your
problem won't be happened.
