NetworkManager was working perfectly on 14 July 2013 but on the first reboot after the NetworkManager update (on ~amd64) I see this in dmesg: NetworkManager[1201]: segfault at 0 ip (null) sp 00007fff20ed1a38 error 14 in NetworkManager[400000+fe000] Naturally I re-emerged the previous version but the segfaulting still happens :( So, what changed? #qlop -l | tail -n 12 Sat Jul 13 09:07:48 2013 >>> app-misc/mc-4.8.9 Sun Jul 14 05:24:52 2013 >>> sys-kernel/gentoo-sources-3.10.1 Sun Jul 14 05:25:16 2013 >>> x11-drivers/xf86-input-evdev-2.8.1 Sun Jul 14 05:27:06 2013 >>> net-misc/networkmanager-0.9.8.2-r1 Sun Jul 14 16:39:43 2013 >>> net-analyzer/wireshark-1.10.0-r1 Mon Jul 15 05:00:27 2013 >>> dev-ruby/json-1.8.0 Mon Jul 15 05:05:41 2013 >>> dev-vcs/git-1.8.3.2 Mon Jul 15 05:25:10 2013 >>> dev-libs/libgee-0.10.2 Mon Jul 15 05:26:00 2013 >>> sys-block/thin-provisioning-tools-0.2.1 Mon Jul 15 05:26:47 2013 >>> app-arch/file-roller-3.6.4 Mon Jul 15 15:21:43 2013 >>> net-misc/networkmanager-0.9.8.2-r1 Mon Jul 15 16:07:54 2013 >>> net-misc/networkmanager-0.9.8.2 Yes, gentoo-sources was updated but I'm still running 3.9.8-gentoo (not 3.10.1 until ati-drivers is updated). I had to use the -f flag for strace to show the segfault, so NetworkManager seems to be starting another thread, which is the process that actually segfaults. I don't know enough about gdb to tell it to follow spawned threads, so I can't give you a backtrace (yet). Any hints welcome! Reproducible: Always
1) The gdb command you want is `thread apply all backtrace full'. 2) Please post your `emerge --info net-misc/networkmanager' output in a comment.

I'm seeing the same issues and the only dependency I see changed is a revbump on libnl from dev-libs/libnl-3.2.22 → dev-libs/libnl-3.2.22-r1. Not sure if this is related or not but providing the small amount of extra information I have.
Today's update 0.9.8.2-r1 -> 0.9.8.2-r2 fixed the segfaulting. Thanks for the gdb help Jeroen. I didn't have time to use it this time, but the next bug is ready to strike any minute now ;)
