opening files with AWN adds invalid launchers

Dragging files onto the AWN dock to be opened by the respective application of the launcher.
if i were to drag a bash script over my gedit launcher on AWN, it'll open up in gedit with no problem, but everytime i do this, it adds an "invalid launcher" to my dock .. though it is not visible on the dock, it still flooded my "Launcher" tab in the preference window..

i think AWN should dedicate a little drag and drop area to add new launchers.. like if i dragged a file onto anywhere on the dock, it would try to open that file with the application my cursor is hovering over, but it would only try to add a launcher if i dragged it over a PLUS icon on the dock or somthing like that
