currently i'm using juk 4:3.5.4-0ubuntu2~dapper1 from kubuntu.org. The problem still exists. I'm using arts and mp3 and ogg files.
at bugs.kde.org i have found a bug describing the same problem: http://bugs.kde.org/show_bug.cgi?id=126032 -- juk: queue plays last track twice https://launchpad.net/bugs/50165 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
