First time i've had this problem.
Trying to burn an iso, have tried the right-click "write to disc" and also through the Brasero front-end and with both burners on my machine. As soon as I finish setting it up to burn at the slowest speed and hit the button to begin the burn, it shuts down immediately and does nothing. Here is the message from /var/log/messages:
Nov 28 15:15:21 localhost dbus-daemon: [system] Rejected send message, 2 matched rules; type="method_call", sender=":1.17" (uid=500 pid=1959 comm="gnome-session) interface="org.freedesktop.ConsoleKit.Manager" member="CanStop" error name="(unset)" requested_reply=0 destination=":1.1" (uid=0 pid=716 comm="/usr/sbin/console-kit-daemon))
Never had problems before, strange. I am running Gnome-Zen-mini 2010.10 (I reckon everybody knows that by now, lol)
Any and all tips appreciated, thanks!
