With latest build xfce4-session doesn't quit session anymore. The window manager quites, the panel quits, the desktop quits, etc, but the session and apps remains until I press ctrl+alt+backspace to kill the X server. This bug is new as it did not occur in previous build. It shows on i386 and x86_64 at least.
Hm, indeed.
Fixed with revision 22787. 2006-08-15 Benedikt Meurer <benny@xfce.org> * xfce4-session/main.c: Revert previous change to reap child processes as the sudo processes are already reaped in the sudo shutdown-helper and the patch attached to bug #2088 causes xfce4-session to hang on logout. Bug #2173.
