can't exec empty command

Hi,
I've started getting the error message 'can't exec empty command'; I've pasted a Backtrace below.
Thanks for any help and sorry in advance, because I think it may have been caused by my stupidity.

Hello,
In Preferences -> Lyrics uncheck Source 'Command' or if you need to take the lyrics from a command configure the command to get the lyrics from.

Sorted.
Thanks, I knew it had to be something that I'd done.
