Created attachment 348192 [details] backtrace of crash with libffi-3.0.13 and gnome-shell-3.6.3.1 I recently did a fresh install of gnome on a system where it had not been run previously. After a couple of months of poking around and trying various things I have narrowed down the problem. Gnome-shell will segfault if libffi-3.0.12 or 3.0.13 are installed. When I finally downgraded libffi to 3.0.11 the segfaults stopped and I am now able to run gnome. That was the only change to the system that has made any difference as far as a segfault or no segfault from gnome-shell. I have attached a backtrace from the crash. #emerge --info Portage 2.1.11.63 (hardened/linux/amd64/no-multilib/selinux, gcc-4.7.2, glibc-2.17, 3.8.11-hardened-Stan x86_64)
