Seems I have the same problem. I'm running sid, after upgrade of gvfs packages devicekit-disks was installed and cdrom detection and automounting is not working anymore. There is a difference original error. On my machine it is broken from the start, no need to fiddle with usb devices.
I have this in syslog (just after restarting): Jan 3 22:54:51 longwa kernel: [ 225.736720] devkit-disks-da[2696]: segfault at c ip 080660da sp bfec67f0 error 4 in devkit-disks-daemon[8048000+28000] On the process list I can see: $ ps -ef |grep devkit root 3707 2801 0 23:20 pts/0 00:00:00 /usr/lib/devicekit-disks/devkit-disks-daemon root 3708 3707 0 23:20 pts/0 00:00:00 [devkit-disks-da] <defunct> I tried to kill and start devkit-disks-daemon manually, but it cdrom detection still does not work.
