Lance, I think I mentioned this before, Nautilus does not handle the mounting, I don't think its some other process causing the additional mount.
Nautilus just displays the mounted gVolume's, those themeselves come from GIO Volume Monitor. GIO Volume Monitor is basically a wrapper around the gvfs udisks2 volume monitor. When you insert a disc, udisks2 will signal gvfs that disc was inserted, gvfs will look at the disc, add it to the volume monitor. and decide if it should be automounted (possibly with help from gio), mount it and add it to the volume monitor. so I would guess the bug is most likely in gvfs or GIO -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1069964 Title: Two processes attempt to mount blank optical discs Status in OEM Priority Project: New Status in glib2.0 package in Ubuntu: Confirmed Status in unity-settings-daemon package in Ubuntu: Confirmed Bug description: This behavior can be reproduced using either a live USB or an installed version of the effected flavors. Simply insert a blank optical disc in the drive. The behavior differs slightly in Ubuntu GNOME as the notification to either Open with CD/DVD Creator or Eject is displayed twice - that is after simply clicking on the X to close that notification it closes but a new duplicate notification appaers immediately. The GNOME Classic session is not effected at all. In all other effected flavors and/or desktop environments a notification appears stating "Unable to mount Blank disc. Location is already mounted". Effected flavors and DE's include Ubuntu w/Unity, gnome-session-flashback, and Ubuntu MATE. Versions effected include Trusty, Utopic, and Vivid. I assume that two separate processes are actually attempting to mount the blank optical media, rather than just the file manager attemting to do so, because both Nautilus and Caja are effected (based on some of the comments below possibly also Nemo). While purely cosmetic in nature I'd certainly be willing to try and troubleshoot this if someone more tech savvy would provide some debugging instructions.
