exaile playlists doesnt work after moving column headers

Binary package hint: exaile

hi, when i try to move the column headers in exaile's playlists the entire playlist became empty and stops working, file -> new playlist doesn't work anymore and i can close the main playlist.
to use exaile again i need to delete .exaile folder in my home directory

how to reproduce:

the standard playlist header row is # Title Artist Album Lenght, try to move lenght and put it between Artist and Album.
