[LAU] lv2 vocoder

[fred]

Hi list,

I'm trying to use lv2 vocoder (launched by "lv2rack" and add an FX) but 
face a problem : everytime I try to change a value in the GUI, the appli 
crash and Debian "insults" in these terms :

/usr/local/bin/zynjacku.py:2652: GtkWarning: 
gdk_x11_atom_to_xatom_for_display: assertion `atom != GDK_NONE' failed
  if file_dialog.run() == gtk.RESPONSE_OK:
/usr/local/bin/lv2rack:198: DeprecationWarning: use 
gtk.Statusbar.remove_message
  self.statusbar.remove(statusbar_context_id, statusbar_id)
Cannot set midi cc map for plugin without engine
python: plugin.c :1292 : zynjacku_plugin_set_midi_cc_map_internal:  
L'assertion « 0 » a échoué.
Abandon

Have search a while but google was not my friend this time... Any help 
really appreciate ! -F
