Hello! This messages is completely normal, it appear when you don't have any custom command configured in guake. In the other hand, in the next upload the manpage will be generate from the upstream files, so you will can search the documentation about custom commands there. (If you can't get anything about that, feel free to submit a bugreport to upstream in github to update the documentation)
