If you receive this error on k3b when querying CDDB database:

"multiple inexact entries" (with a small square character).

Go to the k3b remote CDDB server settings, keep the the entry reading:

http://freedb2.org

add the entry

http://freedb2.org/index.html?lDisc

And move it to the top of the list. That corrected the issue on k3b running on Xubuntu (Ubuntu with xfce) 9.04 Jaunty
