I used gthumb for a long time but somewhere along the line, it started segfaulting on startup. Unfortunately I can't recall what changed. I hadn't updated my system in a good few months and I figured a world update would flush the problem out. It didn't. I'm mainly trying 3.0.2 but I've also tried the new 3.2.2 release with the same result. gdb usually gives a backtrace involving libdbus but occasionally I get one involving glib instead. Even the libdbus backtraces seem fairly random though. I know there are other active threads so it could be some kind of concurrency issue. What's interesting is if I kill all traces of D-Bus first (twm session, system and user D-Bus daemons killed) then it works. I also tried with a completely new user and it still died so it's not something specific to my account. Here's a couple of backtraces and my emerge --info. #0 _dbus_watch_invalidate (watch=0x0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-watch.c:171 #1 0x00007ffff07f975e in free_watches (transport=transport@entry=0x95bca0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-transport-socket.c:83 #2 0x00007ffff07f980d in socket_disconnect (transport=0x95bca0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-transport-socket.c:987 #3 0x00007ffff07f86aa in _dbus_transport_disconnect (transport=0x95bca0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-transport.c:509 #4 _dbus_transport_disconnect (transport=0x95bca0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-transport.c:500 #5 0x00007ffff07f92fd in _dbus_transport_queue_messages (transport=0x95bca0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-transport.c:1165 #6 0x00007ffff07e3294 in _dbus_connection_get_dispatch_status_unlocked (connection=0x95c3a0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-connection.c:4211 #7 0x00007ffff07e3ebc in dbus_connection_get_dispatch_status (connection=0x95c3a0) at /var/tmp/portage/sys-apps/dbus-1.6.10/work/dbus-1.6.10/dbus/dbus-connection.c:4342 #8 0x00007fffe9bcf203 in ??

Please try with fully updated system and gthumb-3.2.3
I was not able to do a big update for a while due to moving house and overheating problems. I now have though and the problem has gone. Who knows why. :)
