I tested in a guest session and I have the same issue. I don't have that file, I have gnome-session-Unity.log. When I click the restart or shutdown button in the dialog, this content gets added to the log:
error : string is not in UTF-8 encoding error : output conversion failed due to conv error, bytes 0xB4 0x67 0x6E 0x6F I/O error : encoder error Each time I start a new session, the "bytes" content is different. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1312223 Title: gnome-session-quit does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/1312223/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
