Version:            (using KDE KDE 3.1.3)
Installed from:    SuSE RPMs
Compiler:          GCC version 3.3 
OS:          Linux

The below looks like an old bug 8647 I think it was, but this differs since it is on KDE-3.1.3 and that it uses QT-3 and that it happens when I press the update button.
Actually I cannot use cddb at all :-( Also if I insert a data cd kscd crashes, and it does not play next file everytime. Sometimes I have to stop the CD and then start it again. Also if I rightclick on the cocking icon and select quit it does not quit, I have to kill it, and sometimes it just requires two klicks on the quit. (Nope I'm not impatiante I've waited for reasonable time)
