Please try to capture a core dump of this. Add the following line to /etc/security/limits.conf: * soft core unlimited Optionally you can change sysctl and set kernel.core_pattern = /tmp/core.%p to change the location where the core dump will be put. After that, do `emerge gdb` and then run `gdb /usr/libexec/gnome-settings-daemon --core /path/to/core/dump/here` (replace the path by the path to the core dump file) after which you can do `thread apply all bt full`, please comment with or attach the full output of the whole gdb process here. Thank you in advance.
I added the line to /etc/security/limits.conf and created a /etc/sysctl.d/local.conf with kernel.core_pattern = /tmp/core.%p , reemerged gnome-settings-daemon with debugging options. After the next reboot and logging with gdm into a gnome-session dmesg says: ... [ 255.612718] EXT4-fs (dm-10): re-mounted.

Created attachment 353786 [details] output of gdb
After setting FEATURES="splitdebug noclean nostrip", reemerging gtk+, glibc, glib, dconf, glib and gnome-settings-daemon the last lines of 'dmesg' are: [ 165.542448] cx88[0]: irq aud [0x1001] dn_risci1* dn_sync* [ 165.542455] cx88[0]/1: IRQ loop detected, disabling interrupts [ 166.647218] gnome-settings-[27004]: segfault at 10 ip 00007f1781b33ab7 sp 00007fffc8e838a0 error 4 in libcairo.so.2.11200.14[7f1781aa0000+10c000] [ 167.174743] gnome-settings-[27178]: segfault at 10 ip 00007f4e18e94ab7 sp 00007fff53830800 error 4 in libcairo.so.2.11200.14[7f4e18e01000+10c000] I have two new core files; root@impala:/root(5)# ll /tmp/core.27* -rw------- 1 gdm gdm 39591936 Jul 21 21:17 /tmp/core.27004 -rw------- 1 gdm gdm 48652288 Jul 21 21:17 /tmp/core.27178 And the output of gdb is in the attachment.
Stack trace suggests this is caused by the same underlying issue as bug #476306 *** This bug has been marked as a duplicate of bug 476306 ***
Maybe the issue disappeared with cairo-1.12.14-r4, at least I do not see after booting any segfaults in dmesg or cores under /tmp: root@impala:/root(7)# genlop -t cairo | tail Tue Jun 18 09:41:07 2013 >>> x11-libs/cairo-1.12.14-r3 merge time: 1 minute and 43 seconds. Tue Jul 16 19:49:34 2013 >>> dev-perl/Cairo-1.103.0 merge time: 21 seconds. Mon Jul 22 08:01:24 2013 >>> x11-libs/cairo-1.12.14-r4 merge time: 2 minutes and 33 seconds. root@impala:/root(8)# ll /tmp/cor* /bin/ls: cannot access /tmp/cor*: No such file or directory root@impala:/root(9)# dmesg | tail [ 77.719491] it87: Beeping is supported [ 118.921945] mount.nfs (26033) used greatest stack depth: 2312 bytes left [ 188.040306] ata1.00: configured for UDMA/133 [ 188.040320] ata1: EH complete [ 188.193702] ata2.00: configured for UDMA/133 [ 188.193715] ata2: EH complete [ 188.282233] ata4.00: configured for UDMA/133 [ 188.282249] ata4: EH complete [ 189.623018] EXT4-fs (dm-6): re-mounted. Opts: user_xattr,commit=0 [ 189.630522] EXT4-fs (dm-10): re-mounted. Opts: user_xattr,commit=0
And the gnome-settings-daemon is running: root@impala:/root(12)# ps -ef | grep sett | grep -v grep rose 27558 27410 0 09:17 ? 00:00:00 /usr/libexec/gnome-settings-daemon
OK, then this was probably caused by the force-enabled xlib-xcb in various cairo ebuilds from the x11 overlay and in cairo-1.12.14-r3 from the main tree. Same as bug #476306.
