  Try to write the simple test program: window with the big button in it and
  button's click should disable button (add no other stuff). If it works
  fine then your bug (GUI frozzing) is not here (where button is).

  No, imho. Signal handler may change the states of the object (imho).

  Well, _imho_ `gtk_widget_set_sensetive` is emmiting signal then called
  (something like "state_changed"). But there _may_ be (and may be not)
  some bugs when emmiting one signal during other signal's handler
  work.
