The "object" parameter is a string to be set by the user in Glade - I have no
idea how you ended up with the string NULL, it should just be empty if you
dont want to specify an object.

Note also when using the "object" (userdata) field, the specified object will
be swapped with the emitting object and thus come first in the callback`s
argument list (the string specified for "object" is a name of another object
in the same Glade file).
