Lest anyone be tempted top replicate my half-assed solution to getting k3b running, I recently tried to burn audio discs, and to put it mildly, they didn't work.
It couldn't find an index - despite all the correct procedures being used, and all the correct looking things happening :-((.
Two wasted Lightscribe CDRs later, I made off to an older box with 13.37 still running and that burned the cd from the same files flawlessly. That's a pain, because that box has the lightscribe cdrom, which slows me down, but such is life.
EDIT: Just to mention, data CDs went fine.
