       Severity: Normal

Description:
When logging out of GNOME using the "Log out" keyboard short cut, I find
that the "save session" warning dialog comes up regardless of the "save
current session" setting.

To reproduce:
1) Under "System->Preferences->Keyboard Shortcuts," Assign a key to the "Log out" keyboard shortcut.
2) Be sure that the "Automatically save changes to session" box is unchecked under "System->Preferences->Sessions"
3) Open some unsupported applications, such as firefox and emacs.
4) Log out using the keyboard shortcut. You will be warned that firefox and emacs do not support session saving. This is the bug---you should not be asked anything about session saving at all because you have "save changes to session" turned off.

Logging out using the GNOME menu from the panel does not produce the
spurious warning---only logging out via the keyboard shortcut causes the
behavior.
