Unable to burn CD-RW in K3b

Hi everyone,

I'm unable to burn CD-RW in K3b (error 
message "cdrecord has no permission to open the 
device").

Apparently, this is a wide-spread problem and there are 
a lot of posts on the internet that deal with it, but 
none of the advice I've found has worked so far.

Any ideas?


I've tried the following:

(1) Updated K3b to the most recent version.

(2) Checked the device name of my CD burner (= sr0), 
and made sure I have access to it (sr0 is assigned to 
the group "drive", and I've added myself to this 
group, and also to "cdrom", just to be sure).

(3) Checked whether I have access to the 
applications /usr/bin/cdrecord, /usr/bin/wodim, 
and /usr/bin/cdrdao. Set the permissions to 775 
(rwxrwxrx) and the ownership/group ownership to 
root/disk.

Please find the K3b error log and details on my work 
environment below.
