A few months ago I changed from Suse 10.2 to 10.3 and I am using KDE 3.5.7. When trying to create a back-up cd with K3b this application quit after having written about 40 MB of data. The data in the debug output (as well as the text) suggest a buffer underrun. I do not know how to avoid this problem. (Under 10.2 I have written several cd-r's using k3b without any problem.)

Is there anyone around who can help me to get going again?
Please find below a selection of k3b's debug output.
Thanks in advance,
Hans.
