This eventually leads to a NULL pointer dereference by gnome- session due to a missing parameter check in gnome_idle_monitor_get_idletime. This renders GNOME Flashback unusable via FreeNX/X2Go in Trusty. Utopic and newer are not affected and the patch is not applicable as the GnomeIdleMonitor implementation was rewritten. Saucy is also affected but is EOL, however I would like to fix this in Trusty as the patch is tiny and IMO obviously correct. This and bug #1251281 are the only bugs preventing GNOME Flashback being used via FreeNX/X2Go in Trusty; and the latter has an easy workaround (divert the acceleration-check helper and replace it with /bin/true) and may be fixed properly soon. I would be happy to prepare a debdiff and fill out the SRU template if a sponsor agrees that the patch is SRUable.
