I too am getting this error. Very easy to reproduce on my system: put an MP3 into the playlist (right-click the song, choose "Append to Playlist"), then right-click on the new playlist entry and choose "Remove from playlist". Happens about 50% of the time.
Here's the backtrace from my system (bugs.kde.org said it didn't have enough information for them...), and using "gdb" to debug the binary gives me "no registers" when I run the "thread apply all backtrace" command.
