@Chris - It looks like your hypothesis was correct.
I've rebuilt gnome-settings-daemon with DEB_BUILD_OPTIONS="noopt
nostrip" to get a full stack trace, and filed a new crash report as bug
692149. Here's the popup_menu_set_group stack frame showing group_number

I've tried repeatedly suspending and resuming my laptop, and also
connecting and disconnecting a USB keyboard while it's running, to try
to trigger this problem. So far, I have been unsuccessful in finding a
reproducer, though it continues to crash as shown in comment #9.

Two other symptoms I've seen which may be related:
X Error of failed request: XI_BadDevice (invalid Device parameter)
Major opcode of failed request: 141 (XInputExtension)
Minor opcode of failed request: 37 (X_ChangeDeviceProperty)
Device id in failed request: 0x17
Serial number of fail
I rebuilt gnome-settings-daemon for debugging, and just had it crash
again. Unfortunately, telepathy-gabble is also still crashing routinely
on my system (bug 668306) and this seems to have prevented apport from
capturing the crash because they both crashed at the same time:

Bug 658777 was a different issue, but still one that could have caused a
similar crash, and I fixed that one already.
We could just initialize the pointer that I think is being wrongly freed
here, but the condition that causes it to happen shouldn't really occur
anyway, so I'd like to try and figu
@Chris, can you tell if this is the same as bug 658777 or not?

Hmmm, it's a shame that the trace doesn't show the value of group_number
in frame #1. If group_number > g, then there would be a condition where
free() is called on an uninitialized pointer, which I guess is what is
happening here (layout_name looks fairly uninitialized to me)
