Hello,

I tried to burn a DVD today with k3b but it failed every time: the debug windows shows these messages
Code:
cdrecord

cdrecord: Can't allocate memory. WARNING: Cannot do mlockall(2).

scsidev: '/dev/sr1'
devname: '/dev/sr1'
scsibus: -2 target: -2 lun: -2
my user is member of groups audio, users, lp, cdrom, video, disk and nobody

If I run k3b from a root console it works without problem. So this seems to be an authorization problem

apparmor is not running.

Any idea?
