I'm not sure what the correct component for this is. I have a reproducible crash here. It happens when I log out from a GNOME session that was started from a remote X display. I.e. I have kdm set to respond to XDMCP, and I have another machine running "X -query $kdm_machine", which I log in using, and when I log in I use GNOME. Logging out causes gnome-session to crash, and the stack ends up in libSM. I can dig up a stack trace if you like. It would be nice to know if it's just me or if someone can reproduce it.
Oh yeah, and it only seems to happen if I use 'Ctrl-Alt-Delete' to logout. Logging out via the menus seems to work fine.
Specifically, it's when I select 'No' or 'Help' when asked if I really want to log out. More info: I don't see this problem when I'm using the kdm machine, only when I'm using a remote X terminal machine (also running Red Hat Linux 7).

Okay, this looks like a gnome-session bug to me now.
I'm confused by the references above to both hitting Ctrl-Alt-Backspace and logging out.... (Ctrl-Alt-Backspace is a rude termination of the session, not logging out.) What is the exact sequence of steps that triggers the problem? Does it happen if you login locally with KDM instead of via XDMCP? What if you use XDM or GDM instead of KDM?
Sorry, I meant Ctrl-Alt-Delete. The exact sequence is: Login via XDMCP. Ctrl-Alt-Delete Hit 'Yes'. (Or 'no', it doesn't actually seem to make a difference..) When I log in locally, not via XDMCP, this doesn't happen.
Ah. Asking around ,the binding of Ctrl-Alt-delete to logout was in some of our betas but didn't make it into the final 7.0, either inadvertently or intentionally - its not clear. If you are running 7.0-final, the binding may have migrated into your ~/.sawfish-custom if you edited other key bindings. Anyways, it should work. I guess I'll try setting up KDM for XDMCP (though not this week) and see if I can reproduce it.
I just installed a machine with 7.0-i386-respin-disc1, and Ctrl-Alt-Delete is bound to logout. :-/
Seems to be fixed since 7.0 - log in (to GDM) via XDCMP, Ctl-Alt-Del to logout, yes/no work fine.
