My pygtk program writes this warning to stderr:
Gtk-Message: Failed to load module "canberra-gtk-module" libcanberra seems to be a library for sound.
My program does not use any sound. Is there a way to disable this error message?
Installing libcanberra is not a solution.
$GTK_MODULESand GTK is doing as it's told: tries to load the specified module.
