[Libburn] New error

[Bryan Forbes]

Ok, coaster starts just fine when run as root (but it can't connect to
gconf because of gnome-session).  If I run coaster with sudo, it works
fine, but it still crashes (even after freeing the burn source after
everything is done).  The permissions on /dev/hdc (which is my cdrom
drive) are as follows:

brw-rw----  1 root cdrom 22, 0 2004-08-23 09:20 /dev/hdc

My user, bryan, is part of the cdrom group, so this doesn't make sense
to me.  I hope it's not a kernel bug.
