cannot drag and drop from file manager to banshee "file system queue"

To replicate:
1: open a media file in banshee from nautilus or thunar.
2: drag another file from nautilus or thunar (or possibly any other file manager) into the "file system queue"

The operation fails. In fact there is no way to add files to the file system queue that doesn't interrupt the current song and skip to the new addition.
