This issue is still affecting other users, and isn't obviously caused by
an issue in the lightdm.conf. Would you care to elaborate here?

Title:
regression with session-cleanup-script triggering without actual
logins
Status in Light Display Manager:
New
Status in “lightdm” package in Ubuntu:
Confirmed
Bug description:
Description:
In Ubuntu 13.10, session-cleanup scripts trigger before a session has
started. Simply clicking between users at the login menu triggers the session
cleanup script. In my particular configuration this triggers a logout script
that runs rsync with the --delete flag. Clicking between users runs the risk
of deleting good files rather than doing backups as in prior releases so I
can't update all my computers until fixed. The example below replicates and
visually shows the effect. While running, the user cannot login until it has
completed and depending on what the logout script does it can cause problems.
Configuration to Replicate:
/etc/lightdm/lightdm.conf
session-setup-script = /usr/bin/gnome-terminal --command "/bin/sleep 10"
session-cleanup-script = /usr/bin/gnome-terminal --command "/bin/sleep 10"
